You obviously have never actually tried to make anything in AI video. It is a parlor trick.Maybe this is a big advance but the current state of AI video is a joke. It is only impressive if you don't actually make anything. It is impressive in a marketing release that is quickly forgot about.
Will Smith eating spaghetti is the dumbest most uncreative thing. You are impressed by it because it is a meme. It is stupid.
I didn't claim to have made anything with AI video. I'm just commenting on how rapidly things appear to be improving from an external viewpoint. We used to give AI crap for failing to generate an appropriate number of fingers on still imagery. Now we're watching multiple minutes of video to find handfuls of discontinuities. The goalposts have shifted pretty far in an exceptionally short amount of time.
I have no idea why you're so intent on coming across bitter about a fledgling technology. A few years ago this demo video would've been indistinguishable from magic. It will continue to improve.
