I don't understand what is the purpose of these bots? Nihilism? Vandalism? At first I doubted when people were saying that such and such comments was AI generated, I didn't understand the goal, the motives so I thought it couldn't be ; but lately I understood how dead wrong I was, we are submerged, I came to realize that we are eaten by a sea of these useless comments.

You can control the major narrative on social media — about anything you want

What we think others around us think has a big effect on our own behavior

the motive is probably more depressing. a normal human who just wants human interaction. people interacting with something "you" wrote just feels nice and people like that stuff.

The goal is likely to be able to astroturf with aged accounts down the line.
