What actually is the point of TDD? - If its to force you to think about edge cases early before you've started building the feature then that sounds like a human trait - If its to be living documentation then that sounds like a human trait

We're going into weird rabbit holes where we've mismatched the tool that is AI which produces extremely cheap code very quickly - with the processes that we've built for slow and expensive to write human-generated code.
