"Working AI is not even remotely on the horizon, it is still completely unknown how it could be done. And this also means it is completely unknown whether a working AI would have issues like motivation, etc.. What is also completely unknown is whether an AI would actually be as smart as a human being and how much computing power it would need to even get to human average level. There is some indication that when you look at interconnect, the human brain is within one order or magnitude of what is possible in this universe. Get larger, and you get slower because of longer ways. Get smaller, and you cannot fit in as many interconnects."
