“Talent” I would say has been invariant with age. I’ve met very young (teens) and people in their seventies who show obvious talent. It also seems to hold, those young talents are still exceptional 20 years later. For knowledge and skills (perhaps we could call that “wisdom”?) that seems roughly linear with age, perhaps plateauing somewhat as skills learned earlier become obsolete. Productivity is kind of another axis, I’ve known prolific and successful developers who I think are of only middling talent, these almost always did better while young. (For context I’m 49 now have been working in software since my late teens.)
