The loneliness epidemic, a constant drip-feed of outrage -- all so that people can make a small amount of money, distracted driving. Nearly every single service becoming worse over time, etc. Since then, the tech CEOs has been sidling up to the halls of power and effectively begging to help destroy privacy as thoroughly as possible.
I certainly know that my life was transformed for the worse by social media. And I don't mean that I went down any rabbit holes -- rather common culture was hollowed out, friends were distracted, friends fell down their own extremist rabbit holes. There is no successful social media company that actually cares about the negative impacts it has had on society. They speak about things such as "providing value" where value = time spent on the platform. They do not care if they ruin lives.
So a few years ago, nearly everywhere you went people are talking about how thoroughly AI was going to transform society. You couldn't go anywhere without hearing it. Of course people are wary. Big tech has been a net negative in very loud, intrusive, and obvious ways in _most_ people's lives. And now they're saying they're going to radically reform society.
The only hope we have is that they're wrong, and their power to change things will be minimal. For sure, if they really how the power to radically change everything, they would change it for the worse and would never spend a moment worrying about the damage they had done.
