I'm deeply skeptical of the "X reimplemented and it was super easy" thing.

The devil is in the detail.

So many edge cases unlikely to be there.

So many details or fine details unlikely to be there.

Years of bug fixes.

If it is literally a drop in replacement and it passes all the tests, and you're replicating something with and extremely thorough test suite, then sure I'll give you the benefit of the doubt.

Otherwise, I don't believe people "rebuilt X product in a week".

God speed to the poor souls that have to make it actually work in the long run:

"I can say that with some authority. Yes, I'm the one who wrote most of this project, but I'm also the director in charge of the entire Cloudflare Workers org, almost 80+ people at this point. I'm not just an IC engineer who has to find time to justify continuing to work on this. I can literally put people on it, and I've already been talking to the team about how to do exactly that."

I don't necessarily buy it either, but TFA talks about the test suite. They basically pulled 2k unit tests and 400 E2E tests from Next and made sure they all passed.

Even then I still don't think passing all the tests means you duplicated something. That would be a naive understanding of the reality of tests.

You think Next.js writes a test for every bug?
