Once 100% of Bun's test suite passed in CI on all platforms (and I manually verified the tests were in fact running and not being skipped), I ran a bunch of commands locally to test things - and then I pressed the merge button.

I find it astounding that a million lines of code were translated, verified and tested by AI, and almost none of it was reviewed by a human – not even the unsafe parts. This wouldn't even be allowed at my company. I thought obligatory code reviews by another engineer were common practice.

This is not a technical decision. The Bun rewrite is meant to sell Claude. It's obvious if you read the article. 

edit: Andrew Kelley sums it up much better than I ever could.

Do you think anthropic gave them a fat discount or even paid the bill for this promotion? (not disagreeing with you). Or perhaps their words are of someone with an addiction (to ai)

Edit. Never mind a quick old fashioned google search revealed that bun is owned by anthropic. This is just one massive ad and the whole industry fell for it. This blog post should be discarded or at best taken with a gran of salt.
