You contradicted yourself here.
Ridley was ~42 when he directed Alien. Scorsese was ~48 when he directed Goodfellas. Gibson was ~36 when he wrote Neuromancer.
They produced their Magnum Opus in middle age (depending on your definition), not in youth. The young are stupid and impulsive. At middle age you’re still energetic but are tempered by life experience.
I stand corrected on those two cases then, I exaggerated, though I did say in their 30s so Gibson checks out. My general point still stands, most people aren't going to produce their best creative work in their 60s, 70s or their 80s. Yes, too young and you lack life experience, but young still have the vigor of youth. So, a 58-year-old Tim Cain isn't going to re-create another Fallout ever again.
