> I pointed Claude Opus 5 at a C codebase I've been working on for years and it immediately found five serious bugs

These 'serious' bugs aren't important if you've been working on this code base for years and only now they pop up. I suspect - although I'm guessing - that probably a hobby project.

Frankly speaking, although this comment is very dismissive about the opinion blog article - assertively stating that this isn't a well-thought-out post - it seems to me that the personal anekdote is irrelevant and that the blog post in question still fully stands.

It's definitely been a hobby project so far, but suddenly its quality has improved a great deal, which I think greatly improves its chances of graduating to being a daily driver.
