Reading this makes me think his pendulum has swung to the other extreme. Experience has decreasing marginal returns. Being 40 doesn't make you 4 times as experienced as an adult as a 25 year old. Being 80 doesn't make you 8 times as experienced. Being a 25 year old you actually have learned a lot about being an adult, and you shouldn't think that time on its own will increase that. It's more the variety of experience that teaches things than time itself, especially if you repeat things for a long time.
