Here's the part nobody mentions in the launch tweet. In the old model, code passed through an experienced engineer before it ever met a real user. That review caught the database left wide open, the secret in the bundle, the route with no auth, the query that dies at scale. It was friction — and it was a safety net.
The new model deleted the friction and the net in one move. Your AI is brilliant at producing something that looks finished — the build passes, the demo works, it deploys. What it can't do is take the adversary's view: where does this break when a real, hostile, or 10,000th user shows up? That question used to be a senior engineer's job. Now it often goes unasked — until production answers it for you.
This isn't an argument to go back. Tickets and big teams aren't coming back, and they shouldn't. The answer isn't less speed — it's putting one layer back.
