Facebook is a misaligned AI whose sole purpose is to put adverts in front of as many eyeball-seconds as possible. It is trying to manipulate us to that end, and with 2.8 billion people to practice on, it’s also very effective; much like junk food, it gives users the sensation of being good even though it isn’t. All of the big networks are trying to do that, with varying degrees of success.
This isn’t about being “socially inept” — if everyone simultaneously agreed to not use social media, we could and would all go back to what we did before[0] — but even knowing the nature of the beast, dismissing its power, its pull, its allure, is a Canute move.
[0] @iamstupidsimple was saying people not on the contact list would be more likely to be forgotten, and that’s true regardless of if the person not on the list is socially awkward or highly charismatic; before Facebook, the list was a piece of paper, but the same applies to that paper list.
