This is my actual hoped-for endgame for the ad based internet. At some point Twitter, FB, etc will be exclusively populated by bots that post ads, and bots that simulate engagement with those ads to drive up perceived value of advertising. They'll use AI to post comments that are really just ads or inflammatory keyword strings to drive further "engagement." The tech companies will rake in billions and billions of dollars in ad revenue, we'll tax all of it and use it to create flying cars, high speed rail, and an ad-free internet closed off to all non-humans. Occasionally a brave ML researcher may venture out into the "internet" to take field notes on the evolution of the adbot and spambot ecosystem.
