The time wasting aspect was never really the issue with social media. It's the way it warps peoples' view of reality without their understanding of that fact. Humans are really really good at being social. We have these skills from millions of years of evolution and existence in social groups. We're really good at filtering out bad actors and building strong communities. But when those communities are algorithmically mediated, chopped up, and repackaged for each individual, it atomizes people and has the effect of replacing actual human interaction with an artificially created situation whose purpose is to profit a single entity. It short circuits all of those safeguards we have to protect our selves and our minds. I refuse now to take part in any form of online social discourse that isn't completely unfiltered, because I understand the dangers. But most people don't, or don't care, and I fear that these behemoth walled garden "curated" experiences will turn out to be the most harmful thing ever done to human civilization.
