> I feel this thought of AGI even possible stems from the deep , very deep , pervasive imagination of the human brain as a computer. But it's not. In other words, no matter how complex a program you write, it's still a Turing machine and humans are profoundly not it.

The (probably correct) assumed fact that the brain isn't a computer, doesn't preclude the possibility of a program to have AGI. A powerful enough computer could simulate a brain and use the simulation to perform tasks requiring general intelligence.

This analogy falls even more apart when you consider LLMs. They also are not Turing machines. They obviously only reside within computers, and are capable of _some_ human-like intelligence. They also are not well described using the IP metaphor.

I do have some contention (after reading most of the article) about this IP metaphor. We do know, scientifically, that brains process information. We know that neurons transmit signals and there are mechanisms that respond non-linearly to stimuli from other neurons. Therefore, brains do process information in a broad sense. It's true that brains have a very different structures to Von-Neuman machines and likely don't store, and process information statically like they do.
