My Human by Design moment: the film turns on one image — a root that snaps. AI produced dozens of versions of that break. Every one of them was technically clean. But the break isn't a visual effect, it's the meaning of the piece: the thing that holds you up is the same thing that holds you down, and cutting it costs something. So the decision was never which render looks best — it was at which exact second does it break. I placed it at 2:57, on the one bar where the drums drop out entirely. AI had no way to know that bar mattered.
