I recently bought my nephew a box of Pokémon cards. I don't play Pokémon, I have no interest in it and frankly it seems kind of dumb. But I would never say that because all I wanted at age 12 were boxes of comic book cards and Magic the Gathering cards. Equally dumb, at least! So I 'get' it, unlike my mother who, though sometimes obliging, thought all of these hobbies were incomprehensible nonsense.
This doesn't seem to be a passing phenomenon. Once you've established a perspective that respects and expects change, there's no law of nature that will magically revert that. That doesn't mean it will be frictionless. And it does require some conscious effort to keep up. I have TikTok on my phone. I rarely use it, but I'm familiar with it and it's not foreign to me. I see it as my task to refuse to let changes in technology or culture become foreign to me. And that task seems vastly easier today compared to the pre-internet era of scarce information, overwhelming monoculture and insular, defensive subcultures.
