Okay so Youtube started recommending these videos in a genre called "HFY" or "Humanity Fuck Yeah" which, as far as I can tell, involves AI narrators reading AI-generated stories over slideshows of AI-generated images and the stories are all military sci-fi where humans are the bestest warriors the galaxy has ever seen and kill stupid evil caricature aliens 1000:1. Once in a while there's a story where an alien race does a massacre to humans which gives the humans an excuse to gloriously commit righteous genocide
Why is this a thing
Who asked for it
Who's watching it
As far as I know HFY originated on 4chan's /tg/ board back in the day as 40k fanwank and of course redditors took it and ran with it making it somehow even more cringe
That explains so much
There's also a "Earth is a hellworld and humans are space orks" genre of Reddit story based on how terrifying Earth wildlife is and how to humans it's normal. A lot of these seem to be based on that genre, just expanded out into hours of slop. As a Star Trek fan I've had to put a ton of effort into purging my recommendations of these.
Unfortunately you're correct, and i'm not surprised somebody decided to mine a 20 year old protofascist meme for AI slop.
The slop economy.
There's also an r/HFY subreddit that's been around for years, so it wouldn't surprise me if it was just AI bots trawling that and mashing it into whatever these videos are. I'm not going to go check either of those things though lol.
