“With the lights out, it’s less dangerous”

Well, I’m writing today on the lapcom, not for any particular specific reason, but just because, as of yesterday afternoon when I was preparing to leave the office, the various strengths (or magnitudes) and directions of the vectors in my brain came together and produced enough impetus for me to pack and then carry the lapcom with me.  After that, there’s much less of an energy barrier in the way of actually writing using the lapcom in the morning.  If I have it with me, I prefer to write using the lapcom rather than the smartphone.

As for the subject/topic of this blog post, well…I don’t know.  I have no idea what to write or what to say, other than to say whatever comes out of my (figurative) mouth here.  I don’t know what I’m going to write ahead of the actual writing any more than you know what my next word will be before you read it.

I guess that’s how conversation happens in real life as well.  People (at least, neurotypical people) don’t tend to script their conversations.  They just start talking, and the process of talking is identical with (or at least part of) the process of forming the ideas in the first place.

You don’t think about that to say before you think and say it, nor do your think about what to think about and say before you think about thinking about and saying things.  One cannot in any literal sense fully plan ahead what one says or thinks, because it would imply an infinite regress.

No, most of the time, expressing one’s thoughts is the first circumstance in which one formulates those thoughts (though of course it might well not be the first time one has had the same or similar ones).  Ideas, and even memories, do not exist fully formed within the brain, as if on some SSD drive; they must be reformed every time they are brought up.

This is part of why memory in humans is so malleable.  All memories bring out not just information from the past, but also color it with whatever information is leading to the memory being recalled at a particular moment.  This feeds back on and can alter the memory over time.

The things that happen with neural nets/deep learning systems/LLMs is teaching us at least some things about how thoughts and minds work in non-linear ways, though it’s important not to draw too many or too literal parallels to actual brains.  For one thing, brains are vastly more efficient than any kind of software/hardware we have.

Though your brain is certainly the most energy-hungry portion of your body, using about 20% of all the calories you burn, this still is only about 20 watts or so.  That’s less than your typical lapcom uses, and far, far less than any LLM or similar system uses.

The brain is also more complex on many levels.  Synapses are not simple binary switches, like transistors; they are more or less continuously variable in the amount of neurotransmitter they release into a synapse, and the number of receptors in the receiving synapse, and the degree to which activation (or inhibition) of those receptors affects the functions of the postsynaptic neuron and how that interacts with other inputs and the basic metabolism and chemistry of the next level of nerve cells.

Those functions are also affected by hormones of various kinds, from peptides to steroid hormones to things like histamine and glutamate that are neurotransmitters and hormones and (some of them) even amino acids.

Then, of course, there are the inputs from the many and various “glial” cells, which are not neurons, but which “support” neurons in the brain, and which (among other things) create the myelin sheaths that allow nerve transmission to happen much more quickly in “white matter”, and so on.  These things can alter and tweak the “weights” in any particular neuron “node” in ways that are more complicated than the nodes and weights in neural nets.

And of course, the scale is daunting.  You have about a hundred billion neurons in your brain (give or take), and each one has connections with 1,000 to 10,000 other neurons, making the total number of synaptic connections in the brain on the order of a hundred trillion to a quadrillion.

Just imagine if every star in the Milky Way galaxy had some kind of hyperspace links to 1,000 to 10,000 other stars.  That would be a complex galactic network.  The brain is this scale of network.  And the synapses, again, are not binary switches like transistors, but are more or less continuously variable within a given range.  Likewise, the impulses traveling down an axon, though binary in a sense (each nerve impulse either happens or does not), actually vary continuously, because it’s the rate of impulses arriving that affects the release of neurotransmitters.  But it’s not the only thing that affects it.

Anyway, this is all interesting stuff, I guess.  Learning about neural nets is fascinating, and is yet another use of linear algebra, matrices and the like (which are also good for General Relativity).  And learning about how gradient descent works in machine learning and so on is interesting and thought-provoking (an amusing coincidence, not an irony).

I’m reading some things about this and trying to pick up on it, just for general understanding.  I doubt that I’ll ever do anything with any of it other than maybe “talk” about it here (which is nearly the only place I talk about much of anything).  But at least it’s interesting.

It’s futile, of course.  But nearly everything I do or have done is or has been futile.  And that’s not just on a cosmic scale, but on a human, day-to-day, interpersonal scale.  Almost all my efforts are either wasted or fully counter-productive.  This is the outcome of something like me trying to do and be good as much as he can; it just tends to be pointless or worse.

None of it matters, though.

Anyway, as often happens with the lapcom, I’ve written too much of nothing today, and that’s irritating to me.  I can’t imagine how annoying it must be to my readers.  At least, the rest of your day will probably be less annoying by comparison with this post, right?

Right?

I guess maybe it doesn’t really work that way.  It’s all just irritating, isn’t it?  It’s irritating that I don’t catch a terminal illness, some kind of deadly but not-too-quick infection or cancer or something.  It would be good to be able to have people know that I was dying, so that if anyone out there is mad enough to want to see me or greet me or say goodbye to me before I die, they could.  I think I would appreciate that.

Odds are, though, I’ll just disappear and be gone someday, perhaps very soon, and almost no one in the world will notice.  Those who do notice will only do so vaguely, because there is practically no one to whom my life is integral or even very strongly connected.  I’m just background static for the most part.  When I go, it will just be good riddance to bad rubbish, as they say.  There’s really no sensibly available better alternative of which I am able to avail myself.

As Kurt Cobain sang, “Oh, well, whatever, never mind.”  He had some good ideas, did Cobain-sensei, and he carried them out.

“A distant ship smoke on the horizon”

Well, it’s here at last:  the final day of June in 2026 AD/CE.  You might say it’s the hospice day for the first half of this year.  Let us try to make its passing as peaceful and comfortable as we can.  I recommend high doses of opioids.

I’m kidding.  I don’t actually recommend such a thing unless one is in severe pain that’s simply not responding to anything else, or unless all the other stuff is simply too toxic.

That’s a big part of the conundrum of opioids.  All the other types of pain medications‒aspirin, other NSAIDs, acetaminophen, lidocaine injections, steroid injections and so on‒have significant systemic toxicities, even at relatively moderate doses.  They affect the stomach, the kidneys, the liver, the local tissues, the endocrine system, etc.  Quite often, one cannot adequately control significant pain for long using them without causing actual, serious, perilous damage to some of the most essential parts of the body.

On the other hand, opioids work.  They directly hit the pain centers/processors, and they actually can relieve pain, even very severe pain.  But they don’t just relieve physical pain.

Somewhat ironically, that’s one of the big drawbacks.  Though they do not cause systemic or organ toxicity, and they will not trigger diabetes, and they will not cause you ulcers (though they may well constipate you), they can affect your behavior and even your character.  Their relief of psychical pain‒sometimes the only such relief some people have felt in a long, long time‒is like their relief of more visceral pain:  it doesn’t actually correct any underlying disorders.

Well, I suppose if the disorder is simply a neurological misfiring such as that which leads to chronic pain, you could say they do at least act on the area that is dysfunctional.  But they don’t cure it.  They almost never correct even neuropathic pain; they simply squelch the alarm for a bit.  And the successful squelching of the alarms tends to require increasing doses, and can lead to dependence and various other issues.

So, there are no very good, relatively simple corrections for significant pain.  This is probably not a surprise, if you think about it.  In some form, at least, pain is among the oldest things in nature and among the most crucial (ha ha)* functions of nervous systems‒and even things that aren’t quite nervous systems, like the internal communication systems in hydra and jellyfish or the analogous systems of plants.

Living bodies don’t readily give up on pain, and they have good reasons.  Pleasure is nice, and is useful, of course, but it’s like having a pretty picture on your wall or having nice, scented candles in your living room or what have you.  No matter how pretty your decorations, you want to have your fire alarms in good working order.  You want them sensitive enough to go off even in situations without real fires‒the classic case of burnt toast, say‒rather than take the chance that they will not to go off in the case of a real fire.  The first error causes annoyance, perhaps requiring you to wave towels at the sensors and open a lot of windows and so on.  The second error can lead to your house burning down, perhaps with you in it.

Of course, these weighted preferences are not absolute.  If one’s smoke alarms were always going off‒or even going off a significant fraction of the time‒one might very well want to wipe out the whole system, to pull all the plugs, to remove all the batteries,  to flip all the breakers to “off”.  Or, indeed, one might simply want to abandon the house entirely, if there were no way to get the alarms to shut the f*ck up.  One might even be tempted to burn the stupid place down, just as a form of petty revenge against it.

There’s a metaphor in all this, I would imagine.  I’ll leave it as an exercise for you to discern it.  I won’t say it’s particularly clever, but it’s not terrible, and it works pretty well.  Anyway, I’ve dealt with this subject before, many times, I’m sure.  It’s fairly tedious, but it does seem to stick in my mind for some inexplicable reason.  I don’t, however, know how to solve the associated problems.

Ah, well.  There are some things humans aren’t meant to know.

Ha ha ha ha!  Sorry, I couldn’t keep a straight “face” while writing something so very stupid.  Humans aren’t “meant” to know (or not to know) anything, anymore than any particular foodstuff “belongs” on a pizza.  People can try to learn and understand anything, even everything, and ultimately, in the long run, as far as I can tell, the more one knows and understands, the better.

If you want to do your best in a game, you would do well to learn the rules as well as you can.  Because, to quote an old car commercial, in real life there is no reset button.  You are the avatar and you are the player, and when you get blasted into nothingness by the depredations of the game’s limitless antagonists, then for the character and for the player, the game is done.  There is no respawning, there are no experience points, there is no starting again at the last save point.

Game over.

*I say “ha ha” because the word “crucial”, related to the Latin for cross (apparently evolving into its modern usage from a metaphor for arriving at a crossroads), is also related to the word “excruciating” which derives from the Latin use of torturing as if crucifying someone.  And that, of course, relates pretty clearly to the topic of pain.

Don’t rent a phase space in a detrimental State

First off, just to get it off my chest (and in case “they” are listening) I want to say that I hate Google’s latest iteration of the symbol for Google Drive.  Before, it looked like a 2-D representation of a three way analog of a sort of Mobius strip.  Now it looks like a poor attempt to draw that previous symbol by a somewhat challenged child who doesn’t understand proportions, let alone how to produce a facsimile of a 3-D shape on a 2-D surface.

No shade on such a child for not immediately and intuitively being able to apply techniques that took centuries for adult artists to discover.  But I do willingly throw shade at the adult graphic designers‒professional artists who have the shoulders of all those previous artists on which to stand‒who produced this new version of the symbol.  It certainly doesn’t look professional.

It seems that almost every time Google updates things for apparently aesthetic reasons, it makes them a bit less good than they were before.  This brings me back, as so many things do, to a point I often make, which could really be considered a theorem when you get down to it:  while all improvement is change, most change is not improvement.

Just look at any phase space representing possible states of reality that are good or bad or neutral from your point of view, and put the “origin” at where you are now.  If you pick any random direction to move in this phase space‒perhaps flipping a coin for each axis (or dimension) and either increasing or decreasing your coordinate in that axis by one unit vector based on the outcome of the coin flip‒and do this for all axes, and repeat if necessary, the odds of you getting anywhere you actually want to go are less than 50%*.  At least, this is so by any pre-chosen measure(s) of goodness that does not deliberately and flagrantly include most of the phase space.

So, this is my exhortation to Google and all other such similar companies, or companies that may face similar perceived pressures:  don’t just change things for the sake of “being a company that doesn’t appear to accept things as being good enough as they are”, especially if your desperate changes are just cosmetic crap.  Focus your energy on things that are “objectively” in need of improvement‒processing speed, ease of use, environmental impacts and other externalities, reliability of backups, security, that kind of hardnosed, practical stuff.

The merely cosmetic crap can be relegated to, I don’t know…the Met Gala or something along those lines, where people make new-looking stuff all over the place for the (apparent) sake of just trying to do something that looks different than anything anyone else is doing.  And, of course, almost everything one sees at such places veers between hilariously awful and just hideously awful.  That’s my judgment, anyway; it’s the only judgment I have available to use.

Okay, so that’s that off my chest.

Except, of course, that it isn’t really “off my chest”.  Unfortunately, human mental states don’t behave like fluids that build up in pressure and volume and then ease when expressed, as if the pressure has been reduced by allowing one to “vent”** it.  It was an old hypothesis (or set of hypotheses) that this was the way mental states work.  It was not a stupid notion at the time, not at all, but it turns out to have been wrong empirically.

Emotions, drives, things like that, are not some kind of metaphorical fluid, but are mental states, somewhat reminiscent of the states of a computer’s RAM (but not exactly like that).  Acting on such states, given the nature of reinforcement that happens in neural pathways, in individual neurons, and in modules of neurons, is if anything likely to reinforce the state on which you are acting.  So, if you feel angry, then venting your anger, acting on it even in a limited way, will not be likely to produce any form of “catharsis”, but will instead make you more likely to get into that state again in the future.

Neural pathways behave somewhat analogously to trails (paths) through a forest or similar place:  the more such paths are used, the clearer, more well-defined, and easier to use they become.

Think about it.  If catharsis were a real thing, a real, causal process, then every time you say or otherwise express the fact that you love someone, you would feel that love less, you would feel it has been released.  But that is not the way things tend to happen (thank goodness).

In fact, expressing emotions you do not feel can make you start to feel them over time.  This is how certain forms of brainwashing and indoctrination work (and it’s probably part of why professional actors so often seem to have such turbulent emotional lives).  Religions have relied upon this fact, sometimes rather openly, for millennia:  say the prayer, enact the ritual, profess the belief, even if you don’t really believe it, and over time, you may actually start to believe.

All right, well, that’s enough from me for today.  I don’t feel very well, either physically or mentally, but I’ll try not to express those facts too much, because I don’t want to reinforce them.  On the other hand, I’m not simply  going to try to change something without having a good reason for the change.  Goodness knows I’ve tried numerous things in many ways, and they have not taken me to regions of my personal phase space that I consider worth inhabiting.

Hopefully you are doing better.

*Unless you do a post-hoc redefining of “good” to include wherever you happen to end up.  But if you do that, then any and every change could be considered good‒even a change that wipes out you and all that for which you care.  Which, honestly, you will kind of deserve, if that word means anything, because you are being willfully irrational and intellectually dishonest.

**Thus the use of that very expression, “to vent”, regarding emotions‒because people wrongly think that things work that way.

O Caesar, these blogs are beyond all use and I do fear them

Hello and good morning.

I thought of a good opening sentence and line for this blog post today, but unfortunately, I thought of it at around one in the morning, during one of my earlier mid-night* awakenings.  These happen more or less every night, at various times.  Sometimes I will start** awake thinking I’ve badly overslept, only to find that I’ve been asleep for less than an hour.  Sometimes the opposite sort of thing happens.  Anyway, one of the hallmarks of things I think during those early midnight awakenings is that I don’t remember their specifics very well.

In other words, I don’t recall what the opening sentence that came to me was.  Given the nature of nocturnal, half-awake thoughts, it might well have been an idiotic starting sentence.  It might have been utter gibberish.  I might not even really have thought of any sentence at all; I might just have had one of those curious activations of certain brain modules without the usual stimulus (such as thinking of an actual sentence) that engenders them.

I suppose it’s somewhat similar to déjà vu, that free-floating feeling of familiarity and recollection that isn’t actually triggered by something familiar but by stochastic activation of areas of the brain that register familiarity and memory.

So, I might have had the feeling that I had just thought of a good sentence to start this blog post, but it was triggered by something that wasn’t related to any actual sentence.  Like Scrooge said to Marley’s ghost, “There’s more of gravy than grave about you.”

The quote was something close to that, anyway; I don’t feel like going to look it up and check.

All this highlights how important it can be not to trust your feelings.  As Radiohead sang, “Just ‘cause you feel it doesn’t mean it’s there.”

Please don’t take this to mean that I think you should repress or ignore your feelings.  Feelings exist for good, sound, biological reasons.  But while they can be good sources of motivation‒indeed, one might argue that any motivation is a feeling‒emotions are unreliable guides for action, especially in the complex modern human world.  It is still certainly worth attending to them, however, rather than merely ignoring them or trying to push them down.

I think fear, in particular, is usually worth noticing and inspecting.  Just because you feel afraid doesn’t necessarily mean that there is some threat or danger nearby, even a merely social one, but nature has clearly arrived at the provisional conclusion that it’s better to be afraid of something that turns out not to be a danger than not to feel afraid of something that is a danger.

Of course, ideally, one would like to feel fear only for real dangers, and only to the degree that they are dangerous, and otherwise to feel fine.  It would similarly be nice to desire to eat and to enjoy eating only those foods that will be most healthy for us at that moment, at that time, and to desire only just as much as we need, and not to want those foods that will be bad for us in the short and long term.

Such perfect accuracy is not even close to being possible, not even for deliberately designed systems, let alone for evolved biological organisms.  And when survival and reproduction are the means by which genes go on into the future, it’s far better (up to a point) to make a type 1 error‒sensing or fearing nonexistent danger‒than a type 2 error‒not recognizing actual danger.

Modern society has discouraged us somewhat from listening to such fears, sometimes out of a desire to be polite, but again, though one should not take such fear, or other emotions, at simple face value, one should listen to them.  One should inspect the feeling and one’s surroundings and circumstances and try to discern why one feels that fear.

If it becomes clear after honest internal and external inquiry that it is a baseless anxiety, a fear without focus, then one can try to shrug to oneself and simply go about one’s business as best one can.  But if there’s a colorable explanation for your fear‒such as a possibly dangerous or certainly unknown person nearby during moments of potential vulnerability‒one should pay attention and act appropriately.  This is especially true for women (and girls), but it applies to men as well.  Gavin deBecker wrote a powerful book about this subject called The Gift of Fear, and I recommend it (this is one of those rare instances in which Oprah and I agree on a book recommendation).

Fear is not the mind killer.  Fear can be the mind sharpener.  The only people who don’t feel fear are fools and corpses.

On the other hand, to go back to the earlier point, emotions are still very blunt and fuzzy instruments, so don’t just let them push you around willy-nilly.  Just because you feel angry, for instance, doesn’t mean that anyone actually did anything to deserve it.  You might be hypoglycemic, you might have had too much caffeine, you might be in pain and/or have had chronic bad sleep***, you might be feeling residual emotional upheaval from something you saw on the news.

The feelings you have can be misleading, but they are not merely random nor are they completely irrelevant or unreliable.  Some of them are positive in and of themselves:  Joy and love are certainly worth not avoiding, for instance.

And middle-of-the-night feelings related to the nebulous impression that one has thought of a good start for a blog post can sometimes be without substance entirely.  And yet, even then, they might sometimes lead more or less directly to a blog post.

When pigs fly and so do fried eggs, things are weird

Well, I did something rather unusual (for me) yesterday, and I’m doing something rather unusual (for me) now.  I bought tickets for the Powerball lottery yesterday.  And this morning I’m composing at least part of this blog post by using voice to text on my phone.

Apparently, when using voice to text. just saying the word “paragraph” doesn’t cause the text to begin a new paragraph.  This is in contrast to what happens when you use the names of ordinary punctuation, and the voice to text turns it into that punctuation, which is actually reasonably impressive.

Okay, well apparently you have to say “new paragraph” to get it to do a new paragraph, but that makes it challenging to describe in writing what you have to say to make it do that.

As for the Powerball ticket thing, well, yesterday we had a customer who didn’t seem to understand how their credit card worked, and we had difficulty getting their purchase to go through.  When they had spoken with their credit card company (supposedly) and told us that it should be clear (for the second time), as I was proceeding to run the card, I said aloud “if this goes through I’m going to buy a lottery ticket”.  It went through.

Then, later in the day, a similar thing happened, and one of my co-workers heard me say what I had said earlier. He said that he would be happy to go in with me on lottery tickets.  I said I don’t know how you even buy them*, but I want to get one of the big ones, the Powerball ticket.  So we said he would chip in $10 and I would chip in $10 and we would buy $20 worth of Powerball picks.

Then, as I was heading out, the boss asked what we were doing.  I told him, and he said he wanted to chip in 10.  So, I bought $30 worth of quick pick Powerball tickets for the drawing that apparently happened last night.  I did not bring them with me to the house, they are waiting at the office.  I do not by any stretch of the imagination expect to win.

Okay, well, to say by any stretch of the imagination is a bit of an exaggeration.  However, as I said to my co-worker, I am probably more likely to survive jumping off the Empire State building than I am to have one of these lottery tickets win.  As he replied, it’s not impossible, though.  He knew he was being silly, but it definitely was a “you go first” moment.

This was a one time thing, done both out of a sense of ennui and a sense of pointlessness; it was just a silly, frivolous thing to do.

Okay, enough with the voice to text stuff.  It’s irritating.  I won’t say that it doesn’t have its charms, but they are limited.  I also don’t like the way it auto-punctuates.  It also doesn’t even seem to know the word “ennui”, if you can stomach that fact (and even if you cannot).

In other news, or “olds” as the case may be, I continue to try to mitigate my chronic pain, with erratic (at best) results.  But I’m still trying.  It’s a profoundly unsatisfying thing to which to have to dedicate a substantial portion of one’s mind and life, but it’s very difficult to ignore or to take in stride.  Even Mr. Spock couldn’t just ignore his pain after he got infested by that flying fried egg thing.

Of course, that makes sense.  Biologically, as I’ve said possibly hundreds of times, it does not make sense for an organism to be able to ignore pain.  Oh, sure, it can be suppressed briefly in emergency situations, and we know that happens.  You can also squelch alarms of various kinds in the industrial world, as you can silence alarms on heart monitors (temporarily) when you know why it’s going off or you know that it’s an artifact.

But important alarms do not bear complete silencing or disconnection‒not without creating significant danger.  That is, unless the alarm is a holdover, a remnant of something that used to be relevant but no longer is so.

Imagine a carbon monoxide alarm, put into a house in the days when they had gas heat and cooking and so on.  This was a reasonable precaution.  But then imagine that it started going off because it detected CO, and in response, the homeowner replaced the gas heat and gas cooking with electric alternatives.  Now there are not even any connections to the gas supply, and as an extra precaution, the owner bought an electric car, so no danger exists of CO poisoning other than some deliberate chemical attack.

And yet…the carbon monoxide alarm keeps going off.  And it doesn’t just do so intermittently; it is constant, though the volume varies a bit.  And by design, it is intrinsic to the very structure and function of all else in the house, so to remove it is either impossible or would disable numerous other, still important systems and still relevant alarms.

That’s a bit like what chronic pain entails.  It ruins some things and taints all things.  After a while, it’s hard to remember what it was like not to be in pain.  And after it has helped drive away everyone important to one‒for no one wants to spend much time around a lost cause‒it can be very difficult to maintain even any semblance of optimism.  You just want to shut that bloody alarm off, even if you have to blow up the house to do it.

Oh, well.  Whataya gonna do?  Maybe if I have won the lottery, I’ll be able to find some newer answers.  I’ll look into that right after I catch the flying pig back from my celebratory skiing trip in Hell.

If I were to win the lottery, I don’t think I would stop working, at least not immediately, and I certainly would not reveal it here‒again, at least not immediately.  Possibly there would be ways to tell, but don’t spend too much effort thinking about them; the chances of winning are almost nanoscopic.

Actually, the chances are much higher of me choosing to jump off the Empire State Building than of winning the lottery.  And the chances of me choosing to jump from a much nearer tall building are higher still.  I even have a building chosen for the purpose, just in case.

Whatever.  It doesn’t matter.  I don’t matter, certainly not in any larger sense, and barely even to myself.

You all matter to me more than that, though, so I hope you do well and have a good day today and a consistently improving set of days hereafter.

*It turns out to be quite easy, of course.  When you’re trying to encourage people to give you their money for nothing, you don’t want to make the process too difficult.

“I find myself growing fatigued, Doctor.”

Hey, everybody.  It’s Tuesday, and here I am writing another blog post.  Huzzah.

I’m rather tired today, which I guess shouldn’t be that surprising, given that I have chronic trouble sleeping.  Still, some days hit me worse than others, for reasons that are probably multifactorial and are certainly difficult to tease apart.  And today, so far, seems to be one of the “I feel more tired than usual by a noticeable margin” days.  You’ve probably all had such days, though you may not have used that specific term for them*.

There is some good news, news that in a way is not world news but is extraterrestrial news, at least temporarily:  the Artemis mission has flown ‘round the far side of the moon, and in so doing has brought humans farther away from Earth even than Apollo 13 did; this is now the farthest humans have ever been.

It’s quite momentous, but the fact of this mission and its (so far) success, raises questions.  I suspect the answers to them are disappointingly trivial, however.  For instance, why was there such a delay in returning to the Moon after the last time in 1972?  The answer to that is at least somewhat clear when one poses the related question:  why did we work so hard to go to the Moon back in the late 60s/early 70s?

Of course, the main reasons were:  primate dominance/hierarchy drives, writ large across the planet.  The Apollo program was, in a barely metaphorical sense, the ultimate dick-measuring contest, and the USA won that one pretty clearly at the time (“Mine reaches all the way to the Moon and back, how ‘bout yours, motherf#cker?”).  The fact that the Soviet Union basically admitted defeat in that region in that round is but one piece among the mountains of evidence confirming that, yes Victoria, humans did indeed land on the Moon.

It wasn’t for purely scientific reasons, though.  In fact, the science at the time took a very distant, rear-facing-storage-area-of-the-station-wagon place compared to the politics that was in the driver’s seat.

Alas, human nature being what it seems to be, perhaps truly amazing innovation and advancement is simply much more likely to occur during conflict (literal and figurative).  Maybe even the Beatles, for instance, were so great at least partly because of the (usually friendly) competitiveness between John and Paul, and also George once he found his considerable mojo.  Ringo was the Samwise Gamgee/Bodhisattva of the group, which seems appropriate for a drummer.

Humans presumably have always had the capacity to make the many scientific discoveries and technological advancements that have occurred in recent centuries.  But they needed to have an impetus before anyone would get anything done.  The two strongest inherent drives are survival and reproduction, and those drives interact and accumulate as humans gather in larger numbers, and they sublimate into national competitiveness‒for wealth and power, for luxury, for prestige, for all that nonsense.

Wouldn’t it be nice if we could deliberately control our motivation?  We have crude means of affecting it already‒caffeine and various other stimulants‒but these are blunt yet jagged tools.  In principle, microelectrodes could be implanted into something like the nucleus accumbens or the reticular activating system or more well-chosen, finely tuned areas of the nervous system.  Then one could use a remote control to give oneself motivation when desired (?).  Presumably, other mental states could be manipulated, encouraged, discouraged, etc.  Just watch out that no one else gets their hands on your remote control!

Maybe it would be better to have a helmet with various directed electromagnets to stimulate specific brain regions at will.  This process is already in use in relatively simple form**, but it could be honed and made more precise and more powerful and useful.  It would be nice to be able to have large-scale motivation that didn’t require the tendency toward large-scale destruction.

It may be an inevitable challenge.  Powerful forces can inherently have very good and/or very bad effects depending on circumstances and, of course, depending on what one means by “good” and “bad”.

Not to say that we couldn’t rather easily be doing things better than we are.  We could.  But…it seems we aren’t sufficiently motivated to do so.

*If you did, that would be truly surprising.  It would be so surprising, in fact, that if you told me it was the case, I would more strongly suspect some manner of deception or illusion or delusion or cognitive bias than that it was actually true (this is reminiscent of Hume’s test for the veracity of supposed miracles).

Our wills and fates do so contrary run, that our devices still are overthrown; Our blogs are ours, their ends none of our own.

Hello and good morning.  It’s Thursday, the 26th of February in 2026, a date that’s only very slightly interesting whether you write it as 2-26-2026 or 26-2-2026.  The fact that you have repeated 2s and repeated 26s is somewhat entertaining, but the zero throws potential symmetries off, making it not nearly as much fun as it could conceivably be.  It’s a shame, really.  I suppose you could write it as 26-02-2026 and rescue a bit of symmetry, but that feels like reaching.  It’s not quite symmetrical anyway, unless one is writing in base-26 or higher.  No, wait, even that wouldn’t work.

I don’t know about what I’m going to write this morning.  That in itself, of course, is nothing unusual.  But I don’t feel that I have much to say about anything at the moment.  I don’t want to get into my depression and ASD and anxiety and chronic pain and insomnia and just general moribund state, because I’m sure no one wants to hear about it anymore, and in any case, there seems to be no way anyone can do anything about it that’s useful, which makes it all the more frustrating.  Writing about it certainly hasn’t cured or even improved my state much, if at all.

Anyway, as I said the other day, you have been put on notice.  Unless you just started reading my blog for the first time yesterday, you’ve no right to act fucking surprised no matter what happens.

Okay, that’s that out of the way.

Now, let’s see, what should I write today?  I could discuss some topics in science, especially physics, though I also have literal, legally recognized expertise in biology, and I know a lot about quite a few other branches of science as well.  This is because I have always been curious about how the world, the universe, actually and literally works on the largest and on the most fundamental scales.

I mean, yes, humans also have their rules and laws and social mores and antisocial morays and all that nonsense, but if you step back even a bit, you can see nearly all human behavior encapsulated by basic primatology.  If you know how the various monkeys and gibbons and gorillas and chimpanzees behave‒especially their commonalities‒human behavior almost always fits right in.  It’s usually not even very atypical.

That doesn’t make the specifics of behavior very easily predictable in any given case, necessarily; then again, we understand an awful lot about the weather and the climate, but the specifics of tomorrow’s weather are tough to predict precisely and accurately, let alone next week’s weather.  Nevertheless, the physics of longer term climate effects of certain kinds of atmospheric gases is almost trivial.

Anyway, humans are too annoying to be very interesting, except in special circumstances.  In this, they are perhaps a bit like cockroaches.  From the point of view of a scientist who studies them, they can be interesting, and from just the right angle and with the right detachment, they can even be beautiful (or some of them can).  But overall, they are merely large masses of highly redundant little skitterers, just doing their shit-eating and reproducing and infesting almost every possible location.

Which type of creature did I mean to describe just now?  See if you can figure it out.

Of course, on closer scales, cognitive neuroscience and neurodevelopment and related stuff, such as “neural” networks, “deep” learning, and other such areas are fascinating.  One thing interesting about them is how all the things that brains and computers and so on are and do are implicit in the laws of physics‒clearly they are some of the things that stuff in the universe can do‒and yet, for all we know, they have only ever happened here, just this once in all the vast and possibly infinite cosmos*.

And for all we can tell, given the human proclivity to plan about 20 Planck units ahead and then after that trust to luck, this could be the only place they occur, and their time will not continue much longer, certainly not on a cosmic scale.

I could be wrong about that…except in the sense that, since I am stating it merely as one of the possibilities, I am not actually wrong at all.  Even if humans do survive into cosmic time scales and become cosmically significant, it will still not be easily debatable that it could have happened that humans would go extinct and would fail to go anywhere but Earth.

Of course, depending on the question of determinism, I suppose one could say that if humans (or their descendants) become cosmically significant then there literally was nothing else that could have happened, at least as seen from outside, at the “end”.

On the other hand, if Everettian quantum mechanics is the best description of the fundamental nature of reality, then in some sense, every quantum possibility actually happens “somewhere” in the universal quantum wave function, though those variations may not include all conceivably possible human outcomes.

Some things that seem as though they should be possible may simply never happen to occur (or occur to happen?) anywhere in the possible states of the universe.  That feels as though it should be unlikely, given how many possible states can be locally evolved in the quantum wave function, but I don’t think we know enough to be sure.

Okay, well, I vaguely hope that this has been mildly interesting and perhaps thought provoking.  It would be enjoyable to get more feedback and thoughts, but I don’t have a very large readership, and only a certain small percentage of people ever seem to interact with written material in any case, so I’m probably lucky to get the feedback that I get.

*With the inescapable caveat that, if the universe is spatially and/or temporally infinite, and if as it seems there are only a finite number of differentiable quantum states in any given region of spacetime (the upper limit of which is defined by the surface area of an event horizon the size of the given region) then every local thing that happens, and all possible variations thereof, “happen” an infinite number of times.  But given that all these regions are more or less absolutely physically distinct and incapable of “communicating” one with another, they can be considered isolated instances in a “multiverse” rather than parts of the same “local universe”.

May the slope of your pain function always be negative

I’ve been thinking about something I wrote in my blog post yesterday.  I had thrown out the thought, in passing, about how it seemed as though all the things in my life that I still do are not things I necessarily do for joy or out of desire to achieve some goal, but rather they are things which are more painful not to do than to do, and so I do them.

There isn’t really a positive motivation—not the pursuit of happiness or improvement or fulfillment or enrichment.  It’s just that the feeling of stress and tension and anxiety (or whatever) regarding the prospect of, for instance, not going to work rapidly becomes worse than the equivalent feelings about going to work.

That’s not a great state of affairs.  Don’t get me wrong; it’s entirely natural.  I’ve written about this many times, this recognition of the fact that the negative experiences—fear, pain, revulsion, disgust, and so on—are the biologically most important ones.  Creatures that don’t run from danger, that don’t avoid injury, that don’t shy away from potential infection and poison, are far less likely to survive to reproduce than creatures that do those things.

We see clinical examples of people lacking some of these faculties—such as those with congenital insensitivity to pain—and while we might envy them a life without agony, it tends to be quite a short life.  Also, they tend to become immobile and deformed due to damage they do to their joints by not shifting position to improve blood flow.

In case you didn’t know, that’s one of the reasons you can’t stand completely still for very long; it’s not good for you.

But many of us, especially in the modern world, have some things that we do for positive experience.  Some of them are dubious, but food, sex, companionship/conversation, singing, dancing, all that stuff, are positive things.  Unfortunately, positive experience cannot be allowed—by biology—to last too long.

As Yuval Harari noted, a squirrel that got truly lasting satisfaction from eating a nut would be a squirrel that lived a very short—albeit fairly happy—life, and would be unlikely to leave too many offspring.

Maybe this is what happens to some drug addicts.  Maybe they really do get satisfaction or at least pleasure from drugs—and maybe that is what ends up destroying them.  At some level, that’s not truly in question, is it?  People who are addicted to drugs forego other pleasures and other positive things, but perhaps more importantly, they fail to avoid many sources of pain and fear and injury.

The reality is probably a bit of an amalgam, I suppose.  I would not say it’s a quantum superposition, though, except in the sense that everything is a quantum superposition (or, rather, a whole bunch of them).

This is one situation in which I think I’m right and Roger Penrose is wrong—a bold claim, but I think a fair one—in that I see no reason to suspect that the nature of consciousness either requires or even allows quantum processes, other than in the trivial sense that everything* involves quantum processes.  But there’s no reason seriously to think that (for instance) neurotubules can even sustain a quantum superposition internally, let alone that such a process can somehow affect the other processes of the neuron, many of which are well understood and show no sign of input from weird states of neurotubules, which act mainly structurally in neurons.

If deep learning systems—LLMs and the like—have demonstrated anything, it’s that intuitive thought** does not require anything magical, but rather can be a product of carefully curated, pruned, and adjusted networks of individual data processing units, feeding backward and forward and sideways in specific (but not necessarily preplanned or even well understood) ways.  No quantum magic or neurological voodoo need be involved.

I think too many people, even really smart people like Penrose, really want human intelligence to be something “special”, to be something that cannot be achieved except within human heads, and maybe in the heads of similar creatures.  Surely (they seem to believe) the human mind must have some pseudo-divine spark.  Otherwise, we oh-so-clever humans are just…just creatures in the world, evolved organisms, mortal and evanescent like everyone and everything else.

Which, of course, all the evidence and reasoning seems to suggest is the case.

Maybe, deep down, there isn’t much more to life than trying to choose the path from moment to moment that steers you toward the least “painful” thing you can find.

Please note, I’m not speaking here about some metaphorical continuum, some number line that points toward pleasure in one direction and pain in the other.  That’s at best a toy model.  In the actual body, in the actual nervous system, pain and fear and pleasure and motivation are literally separate systems, though clearly they interact.  Pleasure is not merely the absence of pain, nor is pain merely the absence of pleasure.  Even peripherally, the nerves that carry painful sensations (which include itching, as I noted yesterday!) use different paths and different neurotransmitters than the ones that deal in pleasure and positive sensation.

Within the brain, the amygdala and the nucleus accumbens (for instances) are separate structures—and more importantly, they perform different functions.  There’s nothing magical about their locations in the brain or the particular neurotransmitters they use.  Those things are accidents of evolutionary past.

There’s nothing inherently stimulating about epinephrine, and there’s nothing inherently soothing about endorphins or oxytocin, and there’s nothing inherently motivating or joyful about dopamine and serotonin.  They are all just molecular keys that have been forged to open specific “locks” or activate (or inactivate) specific processes in parts of other nerve cells (and some other types of cells).  It’s the process that does the work, Neo, not the neurotransmitter.

This brings up a slight pet peeve I have about people discussing “dopamine seeking” (often when talking about ADHD).  I know, the professionals probably use this as a mere shorthand, but that can be misleading to the relatively numerous nonprofessionals in the world.  The brain is not just a chemical vat.  Depression and the like are not just “chemical imbalances” in some ongoing multi-level redux reaction or something, they are malfunctions of complicated processes.  Improving them should be at least as involved as training an AI to recognize cat faces, wouldn’t you think?

But one can do the latter without really knowing the specifics of what is going on in the system.  It’s just sometimes difficult, and the things you think you need to train toward or with often end up giving you what you didn’t really want, or at least what you didn’t expect.

Maybe this is part of why mindfulness is useful (it’s not the only part).  With mindfulness, one actually engages in internal monitoring, not so much of the mechanical processes happening—no amount of mere meditation can reveal the structure of a neuron—but of the higher-scale, “emergent” processes happening, and one can learn from them and be better aware.  This can be an end in and of itself, of course.  But it can also at least sometimes help people decrease the amount of suffering they experience in their lives.

Speaking of that, I hope that reading this post has been at least slightly less painful for you than not reading it would have been.  Writing it has been less painful than I imagine not writing it would have been.  That doesn’t help my other chronic pain, of course, which continues to act up.

*With the possible exception of gravity.

**I.e., nonlinear processing and pattern recognition, the kind many people including Penrose think cannot be explained by ordinary computation, a la Gödel’s Incompleteness Theorem, etc.

Happy Valentine’s Day, you filthy animals.

Well, guess what.  It’s Saturday now, and I’m writing a blog post, which can only mean that I am working today.  At the last minute, the schedule of the office was changed and now we’re working.  And we’re supposedly going to be doing this now every other (meaning alternating ones) Saturday.  But, of course, I worked last Saturday.  And who knows how things will change in the future?  I’m pretty sure not even the boss knows, because he changes the specifics somewhat irregularly, though there are always colorably reasonable purposes behind such changes.

I suppose I could merely have said, “No, I’m not coming in this weekend.  I worked last weekend, I had to walk to the bank after work and I caused my knees and my pain in general to flare up badly, and that problem continues.  I need a fucking break.”  But, of course, I’m not really built quite that way.  I have been too strongly trained to operate on the approach that to shirk going to work is to be a jerk*.

So, here I am, at the office, and it’s the middle of the night.  That’s right, when it got to be time to leave, I was in too much pain to want to ride the train‒it’s not comfortable to sit in, and I usually have to go to the upper levels to find a seat, which is a little exacerbating and occasionally exasperating‒and I didn’t want to pay to Uber back to the house like I did on Monday and then Thursday for the above reasons, so…I stayed here in the office overnight.

I’m tired of being in pain, I can tell you that.  I wish it were the sort of thing one could simply “get used to”, but biology does not tend to select for creatures that can get used to and ignore pain.  That would defeat the whole usefulness of pain.  Make no mistake:  like fire alarms, pain was and is (and probably always will be) terribly useful.  And “terribly” has more than one legitimate meaning here.

The trouble is that in the modern world, we suffer from and yet survive injuries and disorders that would almost never have been survived by our ancestors, and we can live on with the consequences of these injuries and illnesses for decades, but our nervous systems don’t have any clear function that suppresses or diminishes pain after a while.  There’s no selection pressure favoring such a thing.  Even for our ancestors who might have survived to have chronic pain, that problem tended to develop after peak reproductive years had already passed, and so evolution literally could not and cannot detect the issue.

Indeed, it’s just barely conceivable, though by no means demonstrated, that it might be good for male humans who have injuries that hamper them to feel the pain worsen, to have it lead to them removing themselves from the population in one way or another.  When they can no longer be physical providers, in order to increase the share of resources for their offspring and their other kin, they can kill themselves, directly or indirectly, giving the genes they share with close relatives that harbor that tendency a selective advantage.  This is hypothetical, bordering on speculative, but it might make some sense.

This could also be related to female humans being better suited to endure long-term pain than males, since matrilineal support among human tribes is common***, but that’s getting ever more speculative.

Don’t get me wrong; the ideas are plausible.  But it’s just when one’s ideas are strongly plausible‒but not specifically tested or backed by clear and specific evidence‒that one must be especially harsh and strict with oneself.  It’s comparatively simple, and psychologically rewarding, to come up with plausible and logical hypotheses, but even if one is very smart, most of one’s hypotheses are going to be incorrect.  Whether you’re more Popperian or more Bayesian, the crucial usefulness of testing a hypothesis to try to refute it or to see how your credences shift is inescapable.

This mildly interesting digression doesn’t change the fact that I am in searing pain lately, and it doesn’t seem to diminish much for long.  I’m already prone to dysthymia/chronic depression (veering into the acute stage frequently) and anxiety with at least some obsessive compulsive patterns, all of it occurring in a nervous system that is…atypical from the start.

I hate the world.  I hate my body.  I hate the twisted mockery my life has become.  I hate large parts of my mind (but not all of it).  I hate being around people.  I hate being alone.  I really just ought to stop the whole fucking ride and get off.  I just need to work up the nerve and the commitment.  I’m getting there, believe me.

Anyway, I hope you’re having just a lovely Valentine’s Day.

*And to rhyme all the time is to act like a slime and be covered with grime**.

**I know, none of that makes sense.  It’s not really meant to make sense.  I just accidentally did some internal rhyming in a sentence and that stimulated me to do more of it.

***There are good biological reasons for this as well.  Mothers, and therefore maternal grandmothers, all know whether a child is their child or not, so it’s easier to know that it’s a good idea to spend effort and resources on those descendants.  Males, in general, can not be as certain.

There’s hope a great blog’s memory may outlive his life half a year.

Hello and good morning.

First of all, 

Actually, that was second of all, wasn’t it, following my traditional Thursday blog post salutation?  I would almost count that greeting as not being a first thing, however; it is practically automatic, requiring no new knowledge and very little in the way of thought.

Still, there clearly is some caloric expenditure in my nervous system related to doing it, and obviously there are impacts upon the world immediately around me.  And once the post is posted, that impact expands, at least a little.

After a very short while, I suspect, any impact that my writing that particular opening had will be entirely washed out by noise‒even thermal noise at some point.  Like the man said, “The world will little note nor long remember what we say here”.

Of course, the irony is that Lincoln’s speech is what we do remember most from Gettysburg.  By “we”, I mean Americans in general.  I don’t know if anyone in the rest of the world ever reads Lincoln’s Gettysburg Address (though it is a very well written, concise, and moving speech).

And yet, his point is that we ought to remember the battle, and the lives of the soldiers involved in it, and (to my mind) we ought to try to understand the causes of the Civil War and to wonder to what degree the soldiers on each side really were committed to the arguments and ideas supporting their group, or if, deep down, they were just fighting for “our group” against “their group”.*  Yet we most remember, ironically, the words of the man who said that the world would little note nor long remember what he said there.  That was the point I was making.

Anyway, it’s January 1st, the first day of 2026.  Huzzah.  Rah.  Yippee Kiy Yay.

I don’t think it bodes well for the year to start on a Thursday, since this is the day that DentArthurDent had such trouble getting the hang of.  On the other hand, maybe it’s a good thing, since Thursday is and has been my blog day for quite some time, even when I was writing fiction every other weekday.  Probably neither fact matters.

Of course, I am going to work today, despite it being such a universal holiday, and I am not at all happy about it.  I did no celebrating overnight, of course; what on Earth would I celebrate?  But my sleep was not good, anyway, because of all the fireworks and nonsense.  Also, the people with whom I share a house had a big family get together that had barely ended by the time I started writing this.  And, of course, I have chronic insomnia anyway.

It’s actually rather cold here in south Florida‒in the mid-forties right now‒and that makes getting to work slightly less pleasant than usual.  Also, the transit systems are on holiday schedules, and I have a long commute, especially since I have no vehicle.

I also feel that I might be coming down with a cold, but I’m not going to call in sick, because then it would look like I was pretending to be sick so I wouldn’t have to come in on New Year’s Day.  Still, my ears are plugged and my throat is a bit raw, and what might be just my allergies is acting up more than usual.  I’m not really coughing or sneezing, though.  Still, maybe I’ll develop pneumonia and die.  Fingers crossed!

Speaking of ears (I was, you can go back and check), all of a sudden in the middle of the night last night persistent tinnitus began in my left ear.  I have had chronic tinnitus in my right ear for about 18 years now, probably largely due to recurrent ear infections, which have tended to localize to the right side more often than the left.  When you have chronic tinnitus for so long, you get to the point where you…almost…don’t notice it anymore, though I do notice how bad the hearing is in my right ear.

And now my left ear feels very much like the right, with the high, sharp, intense pitch constantly sounding.  Mercifully, it seems to be roughly the same pitch as the noise on the right, a very high D note.  But it is quite annoying, and I fear my hearing is going to be too reduced for me to enjoy music, which is not so much terrifying as horrifying.

Ah, what are you gonna do?  This is life‒it’s a load of crap, but at least you get to die at the end.

I suppose I’ll be writing another post tomorrow, and probably Saturday as well, so you have that (those?) to which to look forward if nothing else.  I don’t know how many people will even read this post today, to be honest.  Will it be fewer than usual?  Will it be more?  Does it matter?

I know the answer to the last question at least.

Again, Happy New Year.  I’ll leave an optimistic-seeming GIF here below for you.  I don’t necessarily share the sentiments, but to be fair, as the Doctor knows full well, great isn’t necessarily good.

*I’m reminded of Faramir’s words (in the movie) regarding the fallen soldier on the field:  “The enemy?  His sense of duty was no less than yours, I deem.  You wonder what his name is, where he came from.  And if he was really evil at heart.  What lies or threats led him on this long march from home.  If he would not rather have stayed there in peace.  War will make corpses of us all.”
