Struck a cord, and I think I managed this prior to LLM in a certain degree.

My primary editor is vim, and for a significant amount of time I was using it almost in puritan fashion, this was before LLM was mainstream.

However, I could not use vim to edit java, even with language server - I tried, but each time I went back to intellij - the rest of the code base in python, ruby and typescript was typically fine.

The reason was two fold, because everyone was using all of the features that intellij had to offer, the code was structured similar to intellij and obviously the java design patterns that was popular at the time. Everything went through factories and managers and interfaces and tracking them through a pure editor was almost impossible. The IDE handled it for you.

But everything else? Things I or others had to build from ground up was built with this cognitive limitation in mind, which means I can fit everything nicely and edit with vim, even without a language server with high efficiency.

Those cognitive limitation is good for the software. It's easy to explain, easy to debug, easy to add and subtract. And I've come to disregard the intellij way, or the current vibe coding till it works that is common everywhere now. The principle is KISS - keep it simple stupid. If AI will not do that, then you have to. It is a simple philosophical question that is more important than ever. And sadly most people still don't realize it - they will happily tack on the next "feature" in with the scaling they didn't need at that time with the design pattern that they don't need at the time and prematurely optimize themselves into cognitive and technical bankruptcy.
