I mean yeah, theoretically. It's nonsense though. Just count the number of individual contributors vs managers at a director level and it quickly becomes apparent that one of the parallel tracks is much, much larger than the other.

I dunno, certainly at IC5 (so I think IC4 now) level at FB, my manager was totally judged on the output of her team, and strongly discouraged from working on her own projects.
Meanwhile, at the same level as an IC, I was working on my own projects but mostly helping others accomplish theirs.
