I thought it was hay or feed of some form, and the horse gas just yanked it's head up in alarm, leaving an arc of feed in the air.
Looking closer, that would have to be sawdust to be that consistent in texture, and even actual bodily fluids don't leave such a sharp edge on a puddle.
I saw that and didn't know horses can't puke, but thought it was fake but because the parking lot was empty of lights, paint stripes for parking, bollards, etc. it's a vacuum behind the horse.
In German there is this kinda obscure phrase „Pferde vor der Apotheke kotzen sehen“, which translates to „seeing horses puke in front of the pharmacy“ used to denote something highly unlikely, because horses can’t puke and especially in front of a pharmacy where they could get something against their nausea.
I don't even think the back legs look too weird. One of the things I've found when trying to spot AI is that often actual images look weird like this just because of the angle / compression etc.
In my company's presentation template, they have an AI-generated image of the inside of a cathedral, with one of our products placed on the ground and then a component of that product in much larger size is floating in the air. And then there's a woman in spiritual clothing looking up to that component, like it's some sort of god.
I do have many questions, but the main one is: What the fuck?
As someone who's 40, and have only seen 2 animes, I have to pat myself on the back for knowing exactly where the source images came from. In retrospect teenage me watched some weird shit.
My memory of it was that a 25 year old gang member decided to become a substitute teacher at a high school for the sole purpose of perving on 16 year olds in high school. Somehow he got transfered to being a full time teacher in middle school, and he had to rescue one of his 12 year old students from making underage porn to support her family, despite being very VERY against doing so morally. Then he swoops in to kick everybodies ass for making child porn.
I also remember they had a running gag of doing this creepy smile thing. Everytime anyone did it, I always got creeped out. And somehow NONE of this raised alarms with me as a teenager, but adult me is like "Wow, in retrospect, that show was pretty fucked up."
There have been a lot of black and white photos of outlandish inventions and alleged WWII experimental weapons that I had never seen before the advent of AI, and I find that more than just a little... fishy.
