I imagine that productivity is also about investment? Someone with an EUV fabrication plant has more productivity than a person with a hammer. If we add in that new technologies make people more productive maybe we haven't had increases in these in sometime. What productivity increases could self driving cars create? Looking at data I found here https://tradingeconomics.com/united-states/productivity https://tradingeconomics.com/united-states/productivity it does not look like there has been a real drop at all, just a jump for the past few years (why is this? initial WFH improvements during the pandemic?) that has dropped back to the same gradual historical increase. I think I'd like to see more analysis to be sure this is or isn't a real trend but I wouldn't worry quite yet.
