Two things:
1. Just because you use AI to write code does not imply there is more code. You can write concise code with AI, you just have to set yourself (and the AI / tools) up for it.
2. The opposite of debt is not value.
I agree that less code is (usually) better.
When it comes to AI folks are far too quick to use models / tools without properly understanding how to get the outcomes they want - then make blanket statements (or complain) when things don't go the direction they want.
All tools are not created equal, some are far more inclined to create an over-engineered mess (Kiro, Cursor). Using agentic coding tools like Cline or Claude Code with the right agent tools, rules and workflows you can achieve high quality outcomes.
