It's hell to maintain for not much gain (for a use case like this at least). As much as it's become a meme, JS and web tech in general has become extremely portable and stable.

I also don't think Anthropic bought bun to make their TUI better. They could have forked it, they bought bun because it incidentally was excellent for the way agents prefer to work and they wanted to capture that audience.

I thought maintenance was free with LLMs???

I think they bought Bun because it was a supply chain risk for them.

Their new flagship product (earning them billions of dollars in revenue per month) was dependent on a platform maintained by a tiny startup.

Buying Bun was a very rational way to reduce that risk, epically since it also got them some top tier engineering talent.

Thinking about that further, I wonder if that was part of the rationale for switching from Zig to Rust that they haven't talked about?

Zig is a much riskier bet for your multi-billion dollar cash cow than Rust is.

But saying that out loud would be rude - they took steps to NOT openly criticize Zig, even after Zig's founder did not show them the same courtesy.
