As someone that has used coding agents extensively for the past year, the problem is they "move fast and break things" a little too well. Turns out that the act of writing code makes you think through your requirements carefully and understand the full scope of the problem you are trying to solve.

It's created the problem that it's a little too easy to ask the AI agent to refactor your backend and migrate to a different platform at any time and have it wipe out months of hard learned business logic that it deems "obsolete".
