Isaac Asimov describes how AI will liberate humans and their creativity (1992)

I think we need to consider what the end goal of technology is at a very broad level.

Asimov says in this that there are things computers will be good at, and things humans will be good at. By embracing that complementary relationship, we can advance as a society and be free to do the things that only humans can do.

That is definitely how I wish things were going. But it's becoming clear that within a few more years, computers will be far better at absolutely everything than human beings could ever be. We are not far even now from a prompt accepting a request such as "Write a another volume of the Foundation series, in the style of Isaac Asimov", and getting a complete novel that does not need editing, does not need review, and is equal to or better than the quality of the original novels.

When that goal is achieved, what then are humans "for"? Humans need purpose, and we are going to be in a position where we don't serve any purpose. I am worried about what will become of us after we have made ourselves obsolete.

You could have said the same thing when we invented the steam engine, mechanized looms, &c. As long as the driving force of the economy/technology is "make numbers bigger" there is no end in sight, there will never be enough, there is no goal to achieve.

We already live lives which are artificial in almost every way. People used to die of physical exhaustion and malnutrition, now they die of lack of exercise and gluttony, surely we could have stopped somewhere in the middle. It's not a ressource or technology problem at that point, it's societal/political
