A developer who professionally survives into their 30s or so needs to make peace that they have statistically exhausted their pool of mentors. If you enjoy mastery of basically anything, you should consider whether it's the time to invert yourself and become the mentor for the next person down the line.
Yea that's fair. I do mentor quite naturally. I just miss the arms-length access to 20 years of experience which I was lucky to have at a previous work place.
There's as much to learn when you are absent of mentors though. Self-sufficiency in the face of ambiguity is a critical skill.
