Isn’t just one guy?

Exactly

This is exactly how Anthropic will market this rewrite towards companies thinking about doing more layoffs.

1 person did a rust rewrite that took 6 days that would have taken hundreds of engineers more than a year to do.

6 days of work to do this. Even if it doesn't end up becoming meaningful, it shows just how tokens and work done will be linked now and in the future. It's going to be hard to compete with someone or a company that has more compute. They will just be able to do things you can't.

I can't help but wonder what this cost in USD assuming you paid standard rates from Anthropic. Can someone even ballpark the price?

I just want to comment that I think it's a good change if we look past the AI involvement.

Bun has had an extremely high amount of crashes/memory bugs due to them using Zig, unlike Deno which is Rust.

Of course, if Bun's Rust port has tons of `unsafe`, it won't magically solve them all, but it'll still get better

And they're clearly marked as `unsafe`, so easy to find, which gives them a nice list of issues to address.

Any stats/source? Not that I think it's false

Looks like Bun owes that to itself to some extent, not solely because of the language

Looks like he did the maintainability performance and test suite checks and made his decision :)
