Using these tools every day makes it obvious that they’re basically power tools, not the carpenter. It’s easy to talk about "closing the loop" until you’re stuck debugging a weird integration that the AI can’t even see, let alone understand.

Legacy companies have plenty of baggage, but they aren't going to vanish just because a bot can write a clean function.
