Look at the power draw of the human brains versus any of the hardware running these models. It’s an order of magnitude difference. Often multiple orders of magnitude.

Part of the reason is a massive focus on GPUs and digital techniques. Some things like math operations are quite fast and accurate to do in a discrete sense when that matters.

The human brain is not discrete though. Nor is it really fully analog.

Specialized hardware beyond GPUs for parallel digital calculations will likely be needed to implement architectures that get actually closer to human levels of intelligence.
