If Anthropic wants to own code development in the future, owning the full platform (including the runtime) makes sense.
Programming languages all are a balance between performance/etc and making it easy for a human to interact with. This balance is going to shit as AI writes more code (and I assume Anthropic wants a future where humans might not even see the code, but rather an abstraction of it... after all, all code we look at is an abstraction on some level).
They will own it, and then what? Will Claude Code end every response with "by the way, did you know that you can switch to bun for 21.37x faster builds?"
"the full platform"
there are more languages than ts though?Acquisition of Apple Swift division incoming?
It doesn't make sense, and you definitely didn't say why it'd make sense... but enough people are happy enough to see the Bun team reach an exit (especially one that doesn't kill Bun) that I think the narrative that it makes sense will win out.
I see it as two hairy things canceling out: the accelerating trend of the JS ecosystem being hostage to VCs and Rauch is nonsensical, but this time a nonsensical acquisition is closing the loop as neatly as possible.
(actually this reminds me of Harry giving Dobby a sock: on so many levels!)
Even outside of code development, Anthropic seems to be very strongly leaning into code interpreter over native tool calling for advancing agentic LLM abilities (e.g. their "skills" approach). Given that those necessitate a runtime of sorts, owning/having access to a runtime like Bun that could e.g. allow them to very seamlessly integrate that functionality into their products better, this acquisition doesn't seem like the worst idea.
