Not sure why you'd take the leap from the idea of technical people managing technical people to "hiring peons who know less than me", that wasn't my intention. Also "as an engineer" was rhetorical -- I'm a manager myself and it's been over 15 years since I've been an engineer. So I do see the point you're trying to make. I still feel the immediate management layer above mid-level ICs should have some level of hands-on knowledge of the system they're developing. At the next level up, I think engineering fundamentals and past technical experience would suffice.

GP made the point that early in your career, your boss should absolutely know more than you do about your technical work, but at some point (fairly early), that inverts and your leader unavoidably knows less than you do about your technical work, because you’re the expert on the team at it and they can’t know more than all 5-8 of their reports like you can when leading 3-5 junior/new devs.

In post 1, you want your lead to preferably know more, someone says that’s not realistic, and in post 2, you profess to not understand their point while changing the goal post to now be “some level of hands-on knowledge”, which sounds like you do understand their point.
