why couldn't Anthropic simply use Claude Code to write Bun over the weekend??

It is open source (MIT license), Claude should have a pretty good start on it already.

I'm confused. I installed claude code with:

    npm install -g @anthropic-ai/claude-code

I thought claude code just used Nodejs? I didn't realise the recommended install used a different runtime.

I've seen a few of these seemingly random acquisitions lately, and I congratulate the companies and individuals that are acquired during this gold rush, but it definitely feels awkwardly artificial.

Quote from the CEO of Anthropic in March 2025: "I think we'll be there in three to six months where AI is writing 90% of the code and then in 12 months we may be in a world where AI is writing essentially all of the code"

Why didn't they just use AI to write their own Bun instead of wasting 8-9 figures on this company? Makes no sense.

From the article, Claude Code is being used extensively to develop Bun already.

> Over the last several months, the GitHub username with the most merged PRs in Bun's repo is now a Claude Code bot. We have it set up in our internal Discord and we mostly use it to help fix bugs. It opens PRs with tests that fail in the earlier system-installed version of Bun before the fix and pass in the fixed debug build of Bun. It responds to review comments. It does the whole thing.

You do still need people to make all the decisions about how Bun is developed, and to use Claude Code.

A single bun? Is that really newsworthy?

Anyone know how much Anthropic paid for Bun? I assume it was at least $26M, so Bun could break even and pay back its own investors, but I didn't see a number in the announcements from Anthropic or Bun.

They switched to recommending this as the installation method back in July:

  curl -fsSL https://claude.ai/install.sh | bash

That install script gives you a single binary which is created using Bun.

Deciding what to Implement

and

Implementing the Decisions

are complementary, one of these is being commoditised.

And, in fact, decimated.

Personally I am benefitting almost beyond measure because I can spend my time as the architect rather than the builder.
