For those unfamiliar with how AI actually works, let's do an easy refresher. Whether pictures, videos, or words, AI — including large language models (LLMs) like ChatGPT — examines large quantities of information to make predictions about what people want when they make a prompt. Then, it reassembles that existing data into its own version of what it's being asked to reproduce. Basically, AI can only reassemble what it's analyzed, but it can cycle through a lot of information very, very quickly.
So what prompt or request did TikTok user @realscarytok make? We've got no clue. Is it even a video based on a prompt from that particular user? We've also got no clue. But presumably, the video — which is actually just an 18-second clip — might have been asked to focus on clawing, crowded hands and forearms with lots of veins, dusty-looking skin, a sepia color tone, and something that looks like dirt funneling human bodies down a tube. And there's that yelling dude with a shifting face. In other words: a typical morning commute on a train or bus.
One person in the video's comments section made a similar gag and simply wrote, "Crowded as hell." Another person took the opportunity to make is assumedly a religious comment and assert, "Believe me hell is worse than this." And yet somebody else took the glummest of approaches and said, "Hell is what we are currently living in."
