It's very likely that in the not-too-distant future there will be entire multi-thousand user communities online that are all just a giant group of fake personas, arguments, ideas, conversations et al - all generated by Ai. There will be debate videos, selfies, deep thoughts, statuses, porn, all of it artificial.
A complete social hierarchy that is entirely fake.
All designed to entice users to enter and explore, think they are talking to, agreeing and disagreeing with, a group of real people, until they are scammed or maybe just endlessly trapped in a fake world.
A honeypot as an entire ecosystem.
Catfishing not as a fake person, but an entire fake world.
