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.

One week to four weeks doesn't make it better.

[antonvs]

Did you miss the part where they said "it hasn't shipped"?

[bastawhiz]

Do you think it won't? How many weeks do you think it'll take to review all that code, or do you admit a 1M line PR is unreviewable?

doesn't make any difference

the point is, users haven't been using it for years, like the original

there is absolutely no way that you can internally test all the use cases that users encounter, especially with such a large code base

That's like saying "It took me a month to hand-make this cupboard. If someone made a cupboard in just one day using a machine, do you think I'd trust it?".

[happytoexplain]

Only you can prevent tangential arguments about analogies.

[ghusto]

Took me a while to understand what you meant by this, and I hope I got it right: If I use a simile or analogie, people will argue about that instead of my point?

Possibly, but my simile was strong enough to be an example. In fact, it's something that happened (still happens to some extent) in carpentry. Note well the absense of any argument against it, but the downvoting.

[insane_dreamer]

you totally missed the point; it's like:

"thousands of people have bought, used and reviewed this hand-made cupboard over the past 10 years, so I can trust that it's good"

vs

"no one has used this cupboard that was made in one day, so I have no idea whether it's good or not"

call me back in a couple of years and we'll talk
