The "What happens" that precedes the "when gifted children grow up" is about what happens to the individuals who were gifted as children. The book doesn't appear to focus on some burden they impose on the rest of society as the result of growing up or how that growing up makes the author feel badly about theirself.
It is the stories of twenty gifted people, not our story about encountering them.
