Not yet. Maybe soon. I'm not placing bets on timelines.

No clue. I'm not there yet. Maybe it's critical. Maybe nothing.

> and other managers

There are a lot of bad managers. I'm halfway not terrible. A significant part of my job is setting technical direction in the same way I did as a staff+ engineer but without the overhead of asking somebody else's permission. Another large part is the "shit shield" function -- somebody thinks they want something, and they either find themselves blocked by me or immediately satisfied with whatever code I'm able to cook up between meetings, not breaking the team's concentration. A huge part is basically just being a teacher, and I love teaching (if it weren't so pessimized by society that might actually be my career). A large part of it is navigating organizational nonsense (for "reasons," I'm rambling, ask if you're curious). And... whatever. My job didn't get easier going into management. Not all of it should have to exist in the abstract, but in any specific company it's still an important function.
