Wow, I feel this deeply. I work with bad software. It is bad because people built it using tools that were designed to "make coding easier". I feel a cold chill imagining the level of institutional cruft that could be allowed to build up with unrestrained ai coding.

With that said - the process of fixing those old mistakes is greatly aided by llms... but you still need to understand what you are fixing, and understanding why giant blocks of code are copy-pasted everywhere, or why convoluted hacks evolved over time as reactions to bizarre underlying untreated bugs is, imo, ultimately a human/organizational/processes problem.

Anyway I think you are bang on.
