I don't use social media because I think it's a net negative in my life. However YouTube I've always justified by following lots of educational content. I've learned a lot of cool things and gained new hobbies just by watching YouTube. One day, leather-working videos popped up on my feed. Soon I was making my own stuff with leather - it was a heap of fun!
I've noticed over the past few years though, that no matter how much I try to tweak the algorithm, I'm just getting mindless junk. And shorts are the worst of it! They're deliberately designed to hook you in, so they're very hard to ignore.
And so YouTube, I have to admit, has become a net negative. Another place for mindless dopamine hits, zombifying us all. I'm so sad about it!
