I really appreciate your optimistic perspective — thank you for posting it. I think it's very easy to be cynical and just assume that things will get worse than they are now, and when you do that, you get to be a wise, world-weary and jaded commentator.
It's actually a lot more work to imagine a better society, because that requires actual ideas for what could be different and how we might get there. Saying, "things will be the same but worse" is a lot easier than saying, "things could be different and better, and here's how". (Full disclosure: I'm stealing this idea from Hope in the Dark by Rebecca Solnit, which I'm currently reading and thoroughly enjoying.)
Notwithstanding its potential to become (or current reality as) a propaganda tool of the Chinese government, based on my very limited experience with it, TikTok actually feels both healthier and stupider (in a vapid entertainment sense) than Facebook and Twitter. I have yet to be outraged by anything I've encountered on TikTok, whereas if I so much as glance at a tweet on Twitter on its web interface, while not logged in, I'm almost guaranteed to be presented with other tweets from people who infuriate or disgust me. Discord also feels healthier than either of those platforms, it's really just a much better version of IRC. As such, perhaps we are already seeing a more healthy ecosystem emerge.
But setting aside the platform side of things, this discussion [1] on the Ezra Klein show calls the current disruptive era "transitory" in the same way that the dawn of other communication media were disruptive and transitory. Eventually, people adjust. Perhaps we are on our way to becoming immune to attention hijacking, outrage politics and FOMO. Speaking for myself, I've certainly become far better at resisting the pull of those phenomena.
