think of all the denied pluralities-to-be; those poor, slighted real estate tycoons. It's not hard to argue we're already in that simulation - first it starts with FB trialling their electioneering-algo with Trump as a proof-of-concept. Then once they work out all the kinks, initiate stage 2, reusing the mechanism!
Arguably, a better plan would be to appear apolitically neutral until a surprise election result occurs, then roll out an algorithm in response to the calls for more filtering...
Agreed. That said, I'd gladly read a book based on that premise.
Already a short story is written about this premise.
