Code review is the real deal for these models. This area seems largely underappreciated to me. Especially for things like C++, where static analysis tools have traditionally generated too many false positives to be useful, the LLMs seem especially good. I'm no black hat but have found similarly old bugs at my own place. Even if shit is hallucinated half the time, it still pays off when it finds that really nasty bug.

Instead, people seem to be infatuated with vibe coding technical debt at scale.
