I'm well older than 30 and couldn't disagree with GP more. I think social media has been an absolute disaster not just for young people, but for society at large.

And, importantly, I don't think it needs to be this way, but is designed to be this way to increase engagement. I remember when I first got on Facebook in the mid 00s and I loved it, and I was able to meaningfully connect with old friends. I also remember when the enshittification began, at least for me, when there was a distinct change in the feed algorithm that made it much more like twitter, designed for right hand thumb scrolling exercises and little actual positive interactions with friends.
