In retrospect, I think the rise of smartphone-based, algorithm-driven social media circa 2012 will be seen as the information-age equivalent of lead poisoning that quietly brainrotted society. It greatly increased the power and reach of disinformation and radicalizing propaganda while destroying the ability of mainstream news sources to moderate or even alert people to the damage being done. There’s a staggering gap in attitudes between people who get their news from social media apps vs. newspapers or even cable TV. And so much of the maliciousness is below the surface, distributed across millions of unique newsfeeds and “for you” pages that the public writ large has very little insight into. If some shell company were airing neonazi recruitment ads on national television, people would be shocked and outraged, but slip it into the feeds of vulnerable people and you can poison an entire generation with hardly anyone noticing until it’s too late.
