Having reached the same conclusions as the author led me to create my first agent to do architecture review, and that's how I learned about the metrics behind good practices that I'd been following for years. LCOM, cyclomatic complexity, that kind of stuff...

It's so easy to ship a lot of code, more effort should be put into ensuring the code is correct, with self-improving feedback loops that involve developers, and dedicated tooling...

But again, a while ago, everything was about prompt engineering, and now you can express you idea vaguely and get a somewhat working result, so this likely will evolve fast as well...
