Essentially, I don't find your progression plausible. I don't think someone, even a genius, is going to approach a second career as effectively as the first, not after having accumulated a lifetime of preconceptions, biases, attitudes, conclusions, and dogma. I doubt even most geniuses have a second wind of genius in them, whether or not they live 50 years longer than they do now.

Since we haven't commonly lived longer than we do now I don't think we can assume that they way it's been is the way it's always going to be.

> a lifetime of preconceptions, biases, attitudes, conclusions, and dogma.

You left out wisdom, experience and perception.
