Re: You humans think very highly of yourselves
@DropBear - There's more to juggling than muscle memory, although it plays an important part. It's hand-eye coordination that matters; just try juggling with your eyes closed. With very limited information about the trajectory of the balls, the brain can extrapolate the trajectories and move your hand to roughly where it needs to be. I think muscle memory is more inportant for throwing the ball on approximately the right trajectory in the first place.
I agree that our brains are just a bunch of specialised tools, but we can combine them to do things that we haven't actually evolved to do. We may not be fully general -- we can't learn everything. But we have a level of generality way beyond any current AI, and general AI is a very hot research area right now.
