I'll post a link to a podcast where the guy responsible for The Social Dilemma documentary is interviewed. I've not watched the documentary but I did watch this entire interview as it's a topic I'm interested in.
In summary, it centres around this one idea;
When you use social media, there is a supercomputer aimed at your nervous system. It's running the latest in artificial learning technology and it has finely tuned the user's addiction to dopamine.
To date, its goals have been predominantly economic. However, the last four years, particularly the last two, have seen user's social media time become more political than ever before.
In terms of reach, social media dwarfs any government's capability.
At some point, the penny should drop that the new MVP in the political realm is AI.
Governments are at least tenuously beholden to someone, social media is beholden to its masters and their bottom line.
