Nobody is actually trying to do that, because it's too hard, they don't know enough about how the brain works, and/or they can't compete on efficiency; pick whichever reasons you like, or add more, but don't pretend that AI researchers have figured out how to simulate a brain.

You're arguing about whether it's possible or not. You're saying it's not possible.

It is possible.

Not really. He said no one who knows anything about the brain thinks it's a binary system.

AFAIK, that is true.

Whether it's possible to replicate what happens in the brain on a binary system or not is a separate thing entirely. It's also not what LLMs are attempting to do.

You're reading him too narrowly. He's answering the question of whether the brain can be modeled (math or magic), and arguing against it. Or maybe he's arguing for a middle ground. Hard to say exactly, he's not very clear.

Except the brain can be modeled with arbitrary precision - so he's got an uphill battle in either case.

TLDR: Yes, he literally said "binary computer" but from the context it's clear he means more than that.

No need to straw man, they aren't pretending anything. It's just a fact about computational theory.

Just because I can't count every grain of sand on Earth, doesn't mean sand grains are uncountable. Those are two distinct facts.

The practicality of a binary brain is distinct from the possibility of it.
