There is no need to be so fatalistic. Sure, AI will upset the apple cart, especially in our little corner, but the economy is built on pricing scarce resources and even if many things become abundant, most other things will remain scarce. There are only so many Manhattan penthouses or Rembrandts (dixit the Economist), so things of value remain, and it will be quite some time before a humanoid can fix the plumbing, so valuable labour will remain as well.

I, for one, am excited to see what the future holds. (side note: I live in a European country with a strong social safety net, I imagine that helps being unafraid)
