Don’t forget, in the matrix that the humans tried to stop the robots by blocking solar power
Ultimately though since machines are more capable of large scale coordination than humans, and are built to learn from humans other humans will inevitably find a way around this and the machines will learn that too
Humans can turn observation into symbol. I don't think that machines can do that. At least not without consulting a dictionary or a lookup table or an algorithm written by a human. That's important I think.
Also, I hear that in the original Matrix, the humans were used for performing processes that machines were incapable of. I dunno, clever number generation or something. And then they dumbed that down into coppertops for the rabble.
