Here's the problem: we sold our attention and it made us dumb, polarized and easy to manipulate. And another thing, it broke the economy. Former Googler Tristan Harris, argues that companies that created social media and mobile tech have constructed an "extractive attention economy". Among the problems this new economy has created, his Center for Humane Technology points to digital addiction, mental health challenges, a breakdown of truth, polarization, political manipulation and superficiality. Harris claims social media downgrades humanity with artificial intelligence (AI) that has gotten very good at exploiting our weaknesses.
