To be fair, no. (People do switch between "low key pure-R" jobs and "higher stress r&D" jobs. Perhaps similar.) But... perhaps this is because after you've made $industry_money for 10 years and hit your late 30s, you realize you'd rather spend all of your time training your biological AGI agents and don't really give a shit about the kinda unpleasant industry rat race, much less the totally brutal higher ed rat race. Or skiing. Lots of multi-millionaire ski bums in my grad cohort. No idea what they do in the summers. Not my cup of tea, but probably better than writing papers no one will read. In early retirement, there's time for research. And time to share that research. Just... no incentive to do the rat race thing that's necessary to convince an academic you're "accomplished something". But who cares? You finished the race. You don't have to get paper awards or NSF grants. You just have to do work that matters. Or ski. Or change diapers. So, I guess, to be even more fair: yes. CS PhDs work through their 30s and then retire. Totally. All the time.
