This makes a lot of sense.

For example, we (and many others) depend heavily on numpy. It's been around for decades and heavily battle tested. If someone came out with a new version of numpy vibe-code rewritten in a week, with assurances that "all tests pass", do you think we would adopt it? Absolutely not. We would have no confidence that there aren't some latent bugs or that we can fully trust the results.

It has nothing to do with AI having rewritten it, it has to do with being battle tested over time. If a team of humans had rewritten it in a week, I wouldn't trust or use it either.

"it was made in a week" gets repeated a lot on HN, but the PR wasn't a release. They've been working on the rust rewrite for more than a month and it hasn't shipped.
