I suspect human intelligence is more than just computations in the brain. A lot of computation I assume most occur 'outside' of the brain in the gut via hormones and protein signalling. I have doubts that you can replicate human intelligence without replicating human biology.

I doubt a lot of computation occurs outside the brain. I'm assuming most of the neurons, nerves, etc in the gut are used primarily for regulating gut health rather than calculating, reasoning, etc.

People have had their intestines completed removed, liver transplants, kidney transplants, stomach stapled, etc without hurting their intelligence or computational ability. I don't think we can replace the brain like we can elements of the gut.

Certainly, the gut, hormones, etc are important to your physical and emotional well being, but I think it's safe to assume that pretty much all over the computation is happening in our brain.

Or even if it were all in the brain, accurately modeling neurons and interactions of neurons, on bajillions of cudas and threadrippers, will probably still take much longer than it takes for the real-life system to do its thing:

  • Modeling the human brain is just one of the directions of the AI research, possibly not the most important one, even, at this point. On the other hand, the "super-intelligence" everyone is thinking about will be nothing like the human mind.

    • I have trouble believing that evolution has been that inefficient. That we can brutally outperform the human brain at 64-bit arithmetic--no surprise. But to accomplish the same with creativity and problem solving? Not holding my breath.
