Well maybe more project/program management than typical people management - you still need someone to organize the work at a higher level, collect the requirements and feedback, check all the compliance boxes, etc.
But I agree that typical line management jobs will evaporate along with the engineering ones.
Replacing managers is a walk in the park compared to replacing programmers. The focus is on programming because that is the benchmark, if we can outsource that to AI, then we can replace everyone.
Better look for architecture and management jobs, only a few select ones would still be allowed into the magic tower.
Naturally after a heavy round of letcode interviews that have nothing to do with writing AI algorithms.
