Software metric are hard, indeed :) Be prepared in a ai-code world when more code does not mean better code.

I've been watching my colleagues' adoption of Copilot with interest. From what I can tell, the people who are the most convinced that it improves their productivity have an understanding of developer productivity that is very much in line with that of the managers in this story.

Recently I refactored about 8,000 lines of vibe-coded bloat down into about 40 lines that ran ten times as fast, required 1/20 as much memory, and eliminated both the defect I was tasked with resolving and several others that I found along the way. (Tangentially, LLM-generated unit tests never cease to amaze me.) The PHBs didn't particularly appreciate my efforts, either. We've got a very expensive Copilot Enterprise license to continue justifying.

In a good or bad way?

I've found AI pretty helpful to write tests, specially if you already have an existing one as a template.

I guess it depends on how much you like things like well-obfuscated smoke tests and mocks that don't accurately simulate relevant parts of the behavior of the module they're mocking.
