I think people are struggling to understand the way the world is changing. Entire modern philosophical contexts are being upended, for personal instance, I have been a big advocate of the philosophy described in Albert Camus’ “The Myth of Sisyphus”, particularly the concept of imagining Sisyphus fulfilled by the tedium of pushing the boulder up the hill, and deriving happiness from the struggle itself. But I bet Camus nor Sisyphus accounted for a self-pushing boulder.

Now what are we to derive happiness from? The joy of a boulder being on top of a hill?

I think that will be the most important thing for this transition, defining new purposes and meanings that people can assign themselves.

I think its fundamentally human nature. At risk of sounding defeatist, I don't think there is another way for us to exist other than in this state of boulder-pushing.

Now, as far as I can tell, we are quite a way away from actually having most/all professions replaced, so for now the answer is rather clear: pick another boulder.
