This article is effectively a troll, because the terms are not defined, and the term "young" is inherently subjective. Meanwhile, the entire project of reducing people to a set of binary labels is - I was going to say "deeply suspect", but actually I think it's an overtly corrupt and immoral way to view people, because it dehumanizes them.<p>In practical terms, I rather like Marcus Aurelius' take on experience. In Meditations he notes that you don't really know what's going on until you're 40. That holds up. You go through phases of thinking you know (and indeed, you really do know different parts of it) at 15, 25, and maybe you think you're done at 35. But no, there are a few more mistakes to be made! There is a great variety of people, interactions, and error modes. The sheer depravity of people, of ALL people, even ones you'd swear were above it, is astonishing. As is the incredibly capacity for warmth, joy, and heroism. It's like humanity is a movie that's about 40-years long, and you have to watch the whole thing, no matter how good you are at anticipating the plot twists.
