Because AI video gen tools fucking suck, lol. Why do you think his new videos all have extremely simple motion, almost no lip-sync, and really repetitive movements? Because these are the easiest ways to not have the thing sperg the fuck out at you, causing you to have to waste a bunch of tokens on another take to try to get usable footage. The telltale mark of an AI-generated video is a fuckton of cuts, and that's done because you're often getting at best a few frames of useful material from any given prompt, so you have to frankenstein them together. Sometimes you god-roll, but that's one among thousands and thousands.
I didn't have a number value at the time, but I had guessed he'd spent thousands when he had his crashout earlier in the year. Grift Shop almost certainly cost this guy more than his last 3 vids shoved together, but at least it was worth it for what came out of it.
