I don't get why Anthropic keeps saying how cool it is that they were able to rewrite bun in rust, I feel like if the model is really that good you wouldn't need a rewrite, you'd be able to create the runtime from scratch.

Code is a fantastic way to capture requirements, particularly iterative product discoveries over time. It's much easier to start with a manifestation of the requirements (and tests of invariants) than starting from base principles.

Productivity theatre is when activity becomes celebrated over outcomes. It's absolutely everywhere in US tech culture.

Rust is a great tool for what they did with Bun. Why make a whole new tool when existing off the shelf tools can do the job?

I like this, it will be a really exciting benchmark to refer back to in a few years
