But hey, maybe he's right. I don't know (or really care) what our next steps are as a society if it's true, but assuming he's telling the truth seems a bit like jumping-the-gun.
The ethics of all this have already blown over. Twitter and Facebook have both been proven to shadowban controversial figures, and no ethical panic ensued. People don't care, they want a Tik-Tok style feed of sugar water and sweet dreams fed to them on an IV drip. If the next step is fabricating fake content (again, considering how many real content creators exist this seems unlikely), then there is no ethical discussion. It's as fake as the AI-corrected profile-picture you shot on iPhone. It's as real as your approximate location being tracked by Walmart WiFi and then processed into shopping habit data to sell to competitors. If you use Facebook or Twitter (or arguably any social media) then you're already being manipulated. They don't need to promote fake content to make you think what they want.
2) We know that shadowbanning exists and is used to contain spammers and other users that a platform doesn't want on their site.
Given that the previous two facts are true, it seems like a perfectly logical outcome that somebody would decide to experiment with some kind of AI powered chatbots to keep shadowbanned users better contained.
Who knows though, I'm willing to entertain anything here in the grand ol' USA. Still, logic suggests that there's a simpler answer here.
I'm sure this would be reasonably effective on the specific goal of occupying these users' time for days/weeks/months/or even years until they realized that they were talking with robots, but it seems like it might have significant negative social consequences for some groups.
For instance, imagine somebody dealing with depression who genuinely needs a human to talk to. Like many in modern society, maybe social media is the only human interaction they have until they get shadowbanned based on tenuous reasons. God, what happens then when depressed and/or unstable people only have robots to talk to for years? What happens when they realize that they've been tricked and feel intense anger/sadness/hopelessness?
This is playing with peoples' lives with fire and shouldn't be an acceptable practice.
