A few years ago, AI-generated videos struggled with even the simplest human actions. One of the internet’s most famous examples was the bizarre clip of Will Smith eating spaghetti, where the hands warped, the pasta looked alive, and every frame felt completely unnatural. What started as a funny AI failure quickly became a symbol of how far video generation still had to go.
Now that same meme has turned into an unofficial benchmark for AI progress. Every new video model is compared against the same challenge: can it finally make human movement look real? In just a short time, AI video has evolved from distorted nightmare fuel to realistic motion, accurate facial expressions, and scenes that are becoming increasingly difficult to distinguish from real footage. The speed of improvement is what surprises people the most, because what feels impossible today may look completely normal tomorrow.
