Gpt4 has been estimated at about 1.8 trillion parameters, so absolutely nowhere near the complexity of a human brain.
Plus I'm sure there's still very much we don't understand about the human brain still. Quantum tubules were de rigeur at one point but I think the theory has since lost credence.
Regarding Artificial and General in AGI - aren't those.. contradictions (as a clue) ?
>most say current AI models are unlikely to lead to artificial general intelligence with human-level capabilities, even as companies invest billions of dollars in this goal
The billions of dollars are at least partly going to develop better models and techniques.
