"what it is that makes us human when computers and machines can educate themselves"
Wait a minute, every single example I've seen, or heard of up to now, of a learning system was specifically trained to learn in one domain.
I have yet to see a machine that can learn chess without any programming, then learn backgammon, then move on to learning knitting and finally learn how to plan and build a wall. Of course, said computer will need arms, at the very least, in order to actually do something, but I think that will be easier than the learning part.
