Most AI editing tools work by detecting audio spikes, transcript keywords, or face-on-camera moments, technically impressive, but it's pattern-matching, not judgment. It can't tell the difference between a loud moment and a genuinely compelling one.
A human editor watches for something different: the line that lands, the pause that builds tension, the exact frame where a cut should happen to keep momentum. That's the gap AI hasn't closed, and it shows up directly in how long people actually watch.
