The difference is when you were a teenager you didn't have algorithmic feeds keeping you glued to the screen like today's youth are.
I'm not on social media, don't watch short-form content etc because I'm an adult and aware of the danger of these things. And I definitely think that parents should teach their kids the same, even if you can't outright forbid / ban it.
I still can't get into scrolling a feed hoping something is interesting. Sure, it happens in short bursts, but usually I'm trying to actually achieve something, even if it's only to satisfy a personal itch or curiosity.
