Also, doesn't each human require some 20-30 years of training from birth in order to be able to answer such questions? This fact seems to be constantly ignored.
The 20 to 30 years is what it takes to get to where you are thinking about something new to humanity.
That is however distinct from no machine being able to do some of the things humans do as of now. It just means that most things they can do, they do better than humans. But first they must be able to do it.
