I've been hearing this for over 5 years now, but social media is still booming, and most people are still on Facebook, and similar apps, and spending more time than ever. It feels weird as if everyone agrees, and knows that smoking kills but continue to smokes more and more.
Well for me I have mostly quit Facebook (other than messenger and using it for event scheduling for game night.) I don't do TikTok, Twitter, or Instagram. I only use Reddit for niche interest/hobbies and deleted all the default subs. I only use Snapchat to talk to a couple of people because its the best way to get ahold of them, and then there a couple of forums like hackernews i lurk and occasionaly post in and that enough for me.
Used in moderation social media is fine. Just like a beer every month or so or a coffee in the morning
