The 100 hours are real and they're heavily back-loaded toward things that aren't features. In my experience the biggest gap isn't code quality, it's operational awareness. You can refactor the code, add types, write tests. But the part that kills you is when something breaks silently in production and you find out from a user three days later. I had a single-character typo in a deploy (traditional code, not AI) that cost $30K because we discovered it from revenue numbers, not an alert. The fix isn't reviewing every line, it's making sure you know when key flows stop working.
