> most people are boring

Nah. Unless your benchmark is "interesting to every person on the planet", in which case, sure. But then, I'd say that following celebrity and politician gossip is far less productive than following the life of my family, friends, and relatives.

Almost every person is interesting to several dozen other people. Exceptions happen, but are relatively rare.

You're correct on the other count: writing takes effort. Not writing to make things interesting, just... writing in general. If you want to summarize your day, it's gonna cost you 30 minutes of brain work. If you want to post to your Instagram reel, Snapchat, or whatever, just point your phone at your surroundings and hold the record button down for 10 seconds or so.
