I think that if that ever comes, it will be because "retirement" is/becomes a time when you still have excess production but you aren't maximizing production, or that instead of 32hr/wk for 10 years, we do 8hr/wk for 40 years, with 3-5 years in there for pivot+retrain or relax+restore+refocus.
I doubt I'll live to see it, tho.
I was hoping to get some additions, thank you.
