1) Mutations can happen before you're born. There's no need to worry about anyone running out of mutations any time soon.
2) Plenty of animals with similar genetic systems reproduce before the age of 20... before the age of 10... etc. and they're having no trouble evolving.
3) In the ever-so-referenced and poorly conceived "plastic period" when we were "evolving on the savannah," anyone over the age of thirty-five would have been a grandfather, or nearly one. So old-age as he's talking about it is really just a construct of the last few thousand years.
He talks about periods where powerful men would have hundreds of children, well into old age (60), and how now fathers are younger now, and can carry fewer mutations. But given the above points, that's no reason to think that humans have stopped evolving. Some dynamics may have changed, but that's it.
I fully expect to never hear about this again.
