I will say that this topic is a common one among people talking about FIRE “financial independence, retire early” — folks who are saving as fast as they can so they can quit working. There are a lot of people who already got there who come back to warn people they won’t necessarily be happy and fulfilled just because they quit the day job. Like, that’s an amazing feeling at first but it probably won’t carry you for 30-50 more years.

The article actually includes some of these examples, but I get the feeling that a lot of readers did not make it past the Brin part.
