If you want to claim that the evolution of the universe can be modeled using a Turing machine/finite state machine, that's probably not terribly far fetched, and I would somewhat agree. But it's a large jump to say "can be modeled by" is equivalent to "is one".
Various physical processes can be modeled by equations, but the rock falling down the mountain isn't an equation. A swinging pendulum isn't an equation. Code modeling a bridge is not a bridge. Ceci n'est pas une pipe.
I hold the view that various models and approximations are just that, and try not to confuse a successful model for what the underlying reality is.
And getting back to the question at hand, even if our brains can be modeled by a Turing machine, and LLMs behave/can be modeled like Turing computers, still does not mean our brains are equivalent to LLMs.
(Note that I'm learning a lot from these debates, even if I disagree with a lot of people. I've started down a more philosophical route and they do get me pondering)
A Turing machine is an abstract mathematical model that is not, as far as I know, physically realizable in the finite universe. A human brain cannot "be" a Turing machine.
"Behaves like" or "can be modeled by"? Possibly, although still not proven. But it cannot "be" one.
This is kind of the point of the thread - being mathematically and scientifically knowledgeable and rigorous can lead to different perceptions and definitions of "reality" (and maybe "truth"). But right now, we need ethics more than ever, and that's largely outside the realm of science.
The reality of a scientist is that everything is made of atoms, which are made of electrons & protons (even that's oversimplifying), there are various biological pathways to do whatever, planets orbit the sun, blah blah.
The reality of the person on the street is that they are hungry and would like a warm place to sleep, out of the rain.
Actual reality, as defined through a lens of science and math (see the sibling comment about filters).
Now, don't get me wrong. I'm a hard scientist (PhD in computational chemistry). Science is useful, necessary, and leads to amazing things. And there should be more dialog between hard scientists and philosophers, ethicists, etc.
But science has blind spots, and is itself built on unproven beliefs (for example, that "true reality", whatever the definition, can even be modeled with math). Scientists should remember that.
“Engineer’s disease” and all that.
Would agents be susceptible to advertising? If humans have issues differentiating ads from real results, and are swayed by TV ads and stuff (they are), then why wouldn't an AI agent.
I kind of assume they would, given how ChatGPT brings up garbage websites sometimes for my questions.
I suppose it comes down to how hyper-competitive some people are, particularly the "greats", that working on software is in the same category as fisticuffs.

TLDR: Making a decision based on only qualitative data, and therefore ignoring qualitative information and observations, can lead to bad outcomes. Not everything that is important can be easily measured.
On the surface, I don't mind the program. However, the implementation is likely to be terrible as we have seen so far. The various agencies tasked with implementing this have already been gutted and are dysfunctional. There is widespread belief that the Genesis mission is just a grift to get government money away from academia and into already-wealthy businesses, and that the call for proposals was a way to mine for ideas that could be stolen.
I was one of the thousands of proposals submitted to the program, which we didn't hear anything about after submission. If the rumors are true, there will only be a pittance of awards this round. So yeah, I'm skeptical that this money will actually end up in the hands of actual scientists.

(Long story short, the administration is slashing the budgets of various NSF divisions to make room X-Labs, despite the Congressional budget stating that is not allowed)
I feel like it's a sign of what's to come - large AI companies with resources academia never had, at some point deciding that selling access to AI is not as important as just doing the research themselves with models inaccessible to anyone else. The end game is all scientific advancement will be done by one or two companies, who will reap all the profits. Why would they give access to a model that develops a cure for cancer when they could develop the cure themselves and get all the money?
(Kind of like Amazon coming out with their own products - use the greater community for ideas, then become a competitor at a scale they often cannot match).
