I find that it was not inefficient, but too efficient. Like our brains weren't ready for that dopamine hit of a Like, Retweet, and other instant feedback of validation.

Same thing with witch hunts online. Don't forget the famous "We did, Reddit!" where people were able to come together as a mob in an easier fashion than ever before (round the clock, and not defined by geographical borders)

We weren't, and still aren't, ready for it so we're struggling. This isn't even really social media specific, but social media's adoption was faster than any other technology I can think of in history. Like dwarfs phone, radio, and TV adoption.
