I have only worked a handful of “traditional” jobs in which ai could do anything major, and even then it can’t replace any job I had (in my opinion). But regardless, in none of my jobs have I had “too many” coworkers. The only time I’d say as much was when a company was hiring to preemptively fill roles they knew were going to be vacant. Although I did notice bigger companies had the perception they were overstaffed, because they also had no communication with lower rungs at all.
