The narrative that machines will "eat" all the jobs leaving the mass of humanity unemployed is an easy to understand story, but it hasn't ever come to pass and probably won't for reasons that don't need to be detailed in this comment.

It is already happening, just take a look at graphs of labor rate participation against productivity. Will it happen to 'all the jobs', no, but will it leave masses of humanity unemployed? Yeah that is already happening, EU unemployment for those under 30 is staggering.
