Bullshit. There's no slippery slope here. You act like these social media companies just stumbled onto algorithms. They didn't, they designed these intentionally to drive engagement up.
Demanding that they change their algorithms to stop intentionally driving negativity and extremism isn't dystopian at all, and it's very frustrating that you think it is. If you choose to do nothing about this issue I promise you we'll be living in a fascist nation within 10 years, and it won't be an accident.
