I really feel this myself.

If I write home-grown organic code then I have no choice but to fully understand the problem. Using an LLM it's very easy to be lazy, at least in the short term

Where does that get me after 3 months? I end up working on a codebase I barely understand. My own skills have degraded. It just gets worse the longer you go

This is also coming from my experience in the best case scenario: I enjoy coding and am working on something I care about the quality of. Lots of people don't have even that
