> good management

I'm not sure I'd apply "good" as a modifier. Being generous, maybe "mediocre."

Good managers know how to find, cultivate, and maximize exceptional people, and that's a difficult job.

I have a feeling that LLMs are going to drastically improve the baseline quality of software. The top end will always require exceptional human involvement, but it will look different.

I disagree. As a manager you're better off accepting a little lower level of productivity from your best employees if it means you don't have embarrassing, to higher management but also to customers, lapses in productivity.
