Well, sure, if you consider 55 as early retirement, I could see how people would be ready to check out and do nothing. These are people that have likely worked full time for the last 30+ years.

What I want to know is what happens at scale if people retire at 30 or 40, or maybe if they never work at all. The idea is that automation might free up people from work entirely. I don't think it's fair to extrapolate data from people who have been working for 30+ years and then had an "early" retirement.
