"Evolution emerges from random mistakes, not intentional design."
I strongly agree with these . The randomness of things paved ways to what we call evolution. The idea of smart A.I's for now is still far in my opinion, but like you I think someday there is this possibility of them emerging. We can not really predict 'when', we can only say that the chances for this scenario to happen isn't slim at all. Thanks for a good read.
