I have full faith, it's the same really smart people that built bun (Jarred and team) that have spearheaded this and are running it. So I have no reason to believe that this was done carelessly.

That said, I'm still shocked and amazed that something this big is possible these days. But as we've seen multiple times now, one of the most important things your codebase can have is a solid test suite.

I will continue to use bun, because at the end of the day, it isn't just the technology, but the talent/people behind the technology that ensures that it will be solid.

And since that hasn't changed, I will still trust bun and its direction.

Also, bun is mostly glue code and sort of "user space" libraries (my words) as Jarred has said on X, most of the underlying runtimes like JavascriptCore, etc weren't rewritten.

So this isn't like 100% of what we think of as bun was rewritten. It's more like the scaffolding and harness.
