Artificial muscle and artificial brains. Just as flexible and street-smart as humans. Als just as cranky, just as error prone, just as greedy.
My firm belief is that we will achieve artificial intelligence in the quite foreceable future. And we shall see that it likes work no better than the real kind. Laziness and intelligence are intertwined.
Of course, this will pose its own set of problems. For the first time, we shall be faced with genuinly non-human truly telligent life. But that set of problem will have nothing to do with the problem that "robots" bring.
