So a human is just a really expensive, unreliable bag of words. And we get more expensive and more unreliable by the day! There's a quote I love but have misplaced, from the 19th century I think. "Our bodies are just contraptions for carrying our heads around." Or in this instance... bag of words transport system ;)

I think the canonical answer is that humans are “bags of mostly water” .

If I'm remembering the full quote correctly, it's "Ugly bags of mostly water."

They are extremely complex, but is that complexity required for building a thinking machine? We don't understand bird physiology enough to build a bird from scratch, but an airplane flies just the same.

The complexities of contemporary computers and complexities of computing-related infrastructure (consider ASML and electricity) are orders of magnitudes higher than what was needed for first computers. The difference? We have something that mimics some aspects of (human) thinking.

How complex our everything computing-related should be to mimic thinking (of humans) little more closely?

I suspect that people instinctively believe they have free will, both because it feels like we do, and because society requires us to behave that way even when we don't. The truth is that the evidence says we don't. See the Libet experiment and its many replications. Your decisions can be predicted from brain scans up to 10 seconds before you make them, which means they are as deterministic as an LLM's. Sorry, I gues…

Libet has only measured the latency of metaconsciousness/cognition, nothing else. It says nothing about free will, which is ill defined anyway.

I've seen that argument repeated ad-nauseum.

It makes sense if you're desperate for free will to be real, but you really have to work for it. Especially when you add in the countless other studies showing that a lot of the reasons we give for our actions, especially in quick or ambiguous choices, are confabulationalist post-hoc constructions. Our own introspection seems mostly to consist of just "making stuff up" to justify the decisions we've already made.

I mean, a reasonable person could argue their way past all the evidence without totally denying it, but "free will" just isn't the simplest explanation that fits the available data. It's possible that free will exists in the same way it's possible that Russels teapot exists.

Slightly unfortunate that "Bag of words" is already a different concept: https://en.wikipedia.org/wiki/Bag_of_words . My second thought is that it's not the metaphor that is misleading. People have been told thousands of times that LLMs don't "think", don't "know", don't "feel", but are "just a very impressive autocomplete". If they still really want to completely ignore that, why would they suddenly change their min…

Yes, subconsciously I kept trying to map this article's ideas to word2vec and continuous-bag-of-words.

All three appear to be technically correct, but are (normally) only incidental to the operation of neurons as neurons. We know this because we can test what aspects of neurons actually lead to practical real world effects. Neurophysiology is not a particularly obscure or occult field, so there are many many papers and textbooks on the topic.(And there's a large subset you can test on yourself, besides, though I would…

Electric current is also quantum phenomena, but it is also very averaged in most circumstances that lead to practical real world effects.

What is wonderful here is that contemporary electronics wizardry that allowed us to have machines that mimic some of thinking, also is very concerned of the quantum-level electromagnetic effects at the transistor level.

I looked up the Libet experiment: "Implications The experiment raised significant questions about free will and determinism. While it suggested that unconscious brain activity precedes conscious decision-making, Libet argued that this does not negate free will, as individuals can still choose to suppress actions initiated by unconscious processes."

It's been repeated a huge number of time since, and widely debated. When Libet first did the experiment it was only like 200ms before the mind become consciously aware of the decision. More recent studies have shown they can predict actions up to 7-10 seconds before the subject is aware of having made a decision.

It's pretty hard to argue that you're really "free" to make a different decision if your body knew which you would choose 7 seconds before you became aware of it.

I mean, those long term predictions were only something like 60% accurate, but still, the preponderance of evidence says that those decisions are deterministic and we keep finding new ways to predict the outcome sooner and with higher accuracy.

Are we not just getting lost in semantics when we say "fly"? An airplane does not at all perform the same behavior as a bird. Do we say that boats or submarines "swim"? Planes and boats disrupt the environments they move through and air and sea freight are massive contributors to pollution.

You seem to have really gone off the rails midway through that post...

A few minutes worth of “personal experience” doesn't really deserve the “personal experience” qualifier.

Why not? It's just a minor example of what's possible, to show the general concept has already started.

> show the general concept has already started

The same way a todler creeping is the start of the general concept of space exploration.
