I'm not so sure that's a fair comparison.

So much "bad" enterprise code evolved into that state over years or even decades of small changes. Meanwhile, last year I got to watch an LLM-authored codebase speedrun itself into a similar state in only a couple months. And I would say that the enterprise code was actually better. It at least did its job fairly reliably. The LLM codebase was riddled with defects, so much so that it ate up all our time and our feature delivery rate ground to a halt.

There are two observations that really eat at me:

1. Studies seem to indicate that agentic coding uses 2-10x as many lines of code to accomplish the same task.

2. One of the only really well-established empirical results in software engineering is the strong association between LOC and defect rate.
