While I’m not saying positively that LLM are the way a brain works, it is worth noticing that the meme argument structure you are using is very often absurd because Turing Machines can be made out of all the things people usually list. People trying to accuse of category shift are very strongly overestimating the strength of that argument in much the same way that people commenting that people who thinks money were cents, nickels, pesos, and dollars are not quite managing to articulate true dissent by pointing out the letters are different.

oh yes, the brain is a Turing Machine! Forgot that one too

[JoshCole]

No you didn’t? You mentioned that argument many times? You can’t talk about pesos, then dollars, then yen, but pretend you forgot to talk about money.

Well it's definitely true that the human brain is Turing complete.

(Trivial approach: It seems fairly unlikely that Alan Turing would not have been able to simulate Turing machine inside his head. :-P )

> Well it's definitely true that the human brain is Turing complete.

That is definitely false. "In computability theory, a system of data-manipulation rules... is said to be Turing-complete... if it can be used to simulate any Turing machine." [0] A Turing machine has infinite memory; the human brain does not.

Technically correct, as expected from HN.

Of course, the technically correct definition would limit the usefulness of the term to just the field of mathematics.

Colloquially, people also say that systems that are obviously finite (due to having to exist in the real world) are also Turing complete. [1]
