Haha, I'm with you. I'm always seeing obvious feel-good engagement slop (AI or otherwise) from Tikok clips reposted on Reddit - like the most obviously fake saccharine pablum A/B tested to grab people's attention and occasionally I can't help but open the comments out of morbid curiosity.
And it makes me feel like a bitter curmudgeon seeing so many people act like it's real and the few people who point out the obvious ad/lying description/AI slop/scripted skit/deceptive editing/etc getting dogpiled for being a cynical Debbie Downer who should shut up and let people enjoy things.
Personally, it doesn't make me feel good to be baited and manipulated for my scarce attention. If anything I find it especially offensive to hijack happiness neurons in my brain for an ulterior motive... that does not make me happy. But increasingly it's looking like I'm in the minority and out of touch with the zeitgeist.
