Yes, but "AI replaces people by improving productivity by 20-50%" is clearly a case of https://en.wikipedia.org/wiki/Lump_of_labour_fallacy. So maybe the "people are losing their jobs" is just totally unrelated to AI . . . but people keep repeating that "companies can do same work with fewer people thanks to AI" nonsense, so there will always be a need to remind them how actual economics work.
This assumes infinite demand which is not a good assumption imo. Especially if people are losing their jobs.
