It's difficult to know what/where the line is for sure, but I think lots of software has shifted away from making people's lives better. Facebook, Amazon, Uber, are doing more negative for humanity than positive I think. Sure, they offer a service that might not've existed before, at least in that iteration or scale, but at what point are the negatives outweighing the positives?
Sure, you "connect" people to friends/family they may not be able to see in person or communicate with regularly. You're also verifiably playing god with information and misinformation, as well as spying on your users, selling their data to other people that want to spy on them, paying employees to view toxic content (which results in PTSD), etc. Is all this worth being able to communicate with people you don't really care about, or that don't really care about you?
