A survey last week put it at 54%. More than half the code shipped today is AI-generated.
In my own work the number is probably higher. AI writes the first draft. AI estimates the work. AI generates the tests. I've written before about the dangerous 20% — the edge cases, the illegal state transitions, the judgment AI quietly skips. That 20% is why I still need senior engineers.
But there's a second 20% problem nobody talks about. Not in the code. Around it.
Sprints. Story points. Standups. Jira boards no one updates. Confluence pages that went stale the day they were written. Every one of those tools assumes a human does the work and another human tracks the work.
That's not my team anymore.
