Not disagreeing with your point in general, but: Not everyone can become an architect or water systems engineer at 50, after having worked a "general assistant" type office job for many years. I think that (and its consequences) might be the biggest short term societal risk of automation in an aging society. How would you solve this problem?
Why can't you become these things at 50? Considering you can become them at 23, having worked perhaps in fast food for a few years prior?
Something something about age and responsibilities and tiredness and not having trained for that, but... it's worth it to think about it, anyway — at least as risk-mitigation for yourself, going forward.
Maybe we'll all end up as plumbers?
