Many reasons

Everyone else is using LLMs to assist their development, which makes it a lot harder to work without them, especially in just building enterprise apps. It doesn't feel like I'm creating something anymore. Rather, it feels like a fuzzy amalgamation of all developers in the training data are. Working with LLMs sometimes feels like information overload. When I see so much code scrolling past as the agent makes its changes, this can be exhausting. Reading this massive volume of code is exhausting. I don't like that the new "power tools" of software engineering mean that my career, our career, is now monetizable. I liked feeling like a craftsman, and that is lost.
