> The human brain is extremely inefficient. That depends heavily on what kind of task we're talking about. The human brain uses just 12 watts, and with that it can still perform certain tasks that a computer using 100 times as much power can't even approach. I get the point you were trying to make. In certain tasks it's extremely inefficient, yes. But in general, it's still crazy how power efficient it is. > Once AI learns to construct efficient mathematical models of the universe There's not going to be just one model. Whether an AI (in the short term) can be more efficient than a human at discovering these efficient mathematical models remains to be seen. It seems like the creativity and discovery needed to do this is exactly what neural nets can be good at, but then you're back to something fairly inefficient (with todays algorithms)
