I don't know what world you're living in but software development has always been a cut throat business. I've never seen true mentoring. Maybe a code review where some a-hole of a "senior" developer would come in having just read "clean code" and use some stupid stylistic preferences as a cudgel and go to town on the juniors. I'm cynical enough to believe that this, "AI is going to take your programming job!" is just a ploy to thin out the applicant pool.
