The people that he mentions at the beginning of the article who have left have all peaked in their careers. The real loss would not be of people who have peaked leaving but of people who haven’t peaked yet leaving.

No, it is people who haven't peaked yet not even coming in the first place.
It’s like if Bill Gates leaves Seattle. Nothing happens because Gates is done in his career.
