even if technically AI could take over the world, it is not practical.
we look at computers (and in general AI )in a way that they are like humans but not as sophisticated as humans, I beg the differ, Humans are totally different, and the reason that I think AI is not going to take over the world is they AI can't emulate ambitious and selfishness(two important factors that make humans to seek the power, go on wars, commit the crime, do evil, etc...), and without these two factors there is no motivation for super computers and AI to take over this messed up world
