This is akin to claiming that a tic-tac-toe game is turing complete since after all we could simply just modify it to make it not a tic tac toe game. It's not exactly a clever argument.

And again there are endless things that seem to reasonably defy turing computability except when you assume your own conclusion. Going from nothing, not even language, to richly communicating, inventing things with no logical basis for such, and so is difficult to even conceive as a computable process unless again you simply assume that it must be computable. For a more common example that rapidly enters into the domain of philosophy - there is the nature of consciousness.

It's impossible to prove that such is Turing computable because you can't even prove consciousness exists. The only way I know it exists is because I'm most certainly conscious, and I assume you are too, but you can never prove that to me, anymore than I could ever prove I'm conscious to you. And so now we enter into the domain of trying to computationally imagine something which you can't even prove exists, it's all just a complete nonstarter.

I'd also add here that I think the current consensus among those in AI is implicit agreement with this issue. If we genuinely wanted AGI it would make vastly more sense to start from as little as possible because it'd ostensibly reduce computational and other requirements by many orders of magnitude, and we could likely also help create a more controllable and less biased model by starting from a bare minimum of first principles. And there's potentially trillions of dollars for anybody that could achieve this. Instead, we get everything dumped into token prediction algorithms which are inherently limited in potential.

No, it is nowhere remotely like that. It is claiming that a machine capable of running a Turing machine is in fact capable of running any other Turing machine. In other words, it is pointing out the principle of Turing equivalence.

Show us one. We have no evidence of any single one.

Unless you can show that humans exceeds the Turing computable, "consciousness" however you define it is either possible purely with a Turing complete system or can not affect the outputs of such a system. In either case this argument is irrelevant unless you can show evidence we exceed the Turing computable.

This is fundamentally failing to engage with the argument. There is nothing in the argument that tells us anything about the complexity of a solution to AGI.

LLMs are not capable of simulating turing machines - their output is inherently and inescapably probabilistic. You would need to fundamentally rewrite one to make this possible, at which point it is no longer an LLM.

And as I stated, you are assuming your own conclusion to debate the issue. You believe that nothing is incomputable, and are tying that assumption into your argument as an assumption. It's not on me to prove your assumption is wrong, it's on you to prove that it's correct - proving a negative is impossible. E.g. - I'm going to assume that there is an invisible green massless goblin on your shoulder named Kyzirgurankl. Prove me wrong. Can you give me even the slightest bit of evidence against it? Of course you cannot, yet absence of evidence is not evidence of absence, so the burden of my claim rests on me.

And so now feel free to prove that consciousness is computable, or even replicating humanity's successes from a comparable baseline. Without that proof you must understand that you're not making some falsifiable claim of fact, but simply appealing to your own personal ideology or philosophy, which is of course completely fine (and even a good thing), but also a completely subjective opinion on matters.
