As a lead or principal dev you are constantly shuffling old problems off to new people so you can stay on top of new or broadening problems. It’s a lot easier to delegate problems if you’ve made them smaller during your watch. I’ve seen enough of the consequences of failure to delegate. But it takes a bit of self awareness to see how being a bottleneck affects other people while or after you are busy unblocking them.

Volunteering to be preempted by broken systems more often is a sucker’s bet. Solve problems so they stay solved. It’s more work now, but reduces the interest rate on past work so you can get new things done.
