I have been telling people lately that I feel like I'm losing my mind. And I'm not even someone who has leaned into AI coding that much either; I've just tried to learn the tools since Claude got "good". But my inherent laziness, which was always flattered as something that makes me a good programmer, has made me unable to use the tools with the required discipline. The result is that I have not thought deeply about the software I write for around 3 months. Every additional week that goes by without me doing a refactor or serious feature addition saps my confidence. I know I can still code. But I feel worried that I can't. Today I am refactoring a 4k LOC AI-written rust codebase. I don't know rust, but I will finally learn it today. And I can already tell the end result will be 50% the size and immeasurably more coherent.
The lack of refactoring when using AI tools is definitely a concern. I've only ever seen lines of code go up.
