Isn't this a case of missing the trees for the forest though? The human brain is not an LLM, and an LLM is not intelligent in the same way as a human brain.

However, an LLM is a prediction machine, prediction IS at the very least one (or the most fundamental) element of intelligence. The brain most surely contains at least some kind of simulacrum of a prediction machine. How that prediction machine is used or wrapped is another matter.

If I said to you: "Blue blue blue, the color of my car is red", would you have absolute confidence in your prediction that my car is red? Or would the way I phrased that sentence make you slightly uncertain, and wonder if there's some miscommunication going on here?

LLMs are awesome awesome tech!

A lot of people seem to think it's human level intelligence.
