Earlier quoted context omitted.
The extreme personalization of the internet/modern life can lead to a feeling of isolation. I recently was on a plane with broken inflight entertainment, so all you could watch was a single movie in lock step with everyone else. When the movie ended, there was a weird sense of camaraderie; "we are all stuck in this tube and we all just sat through that mediocre movie".
I was honestly kind of shocked to find out a coworker watched a couple of the same YouTubers I do. It's probably just because my interests are obscure but my assumption has always been I live in my own bubble. Even my friends don't consume anything like the same media I do, going back to the early aughts. About once a month I'll be watching a YouTube Short and my wife will yell out "Hey, I saw that on Tiktok"
You think, that's just a joke?
Just wait until you're married...
