Bun's unreleased Rust port has 13,365 unsafe blocks (opens in new tab)

It seems that this era is a marketing experiment for Mythos.

We're running forward without any idea of how we can get agents to write code that is even remotely safe or secure. It _will_ blow up with increasingly large blast radiuses.

So don't port. Write a better version.

In some cases it's impossible. C to TCL almost fine, C mapped to Scheme, or Prolog, hell awaits, because Scheme's functions can reduce tons of redundant functions to a single one.

But if that's the goal then I _think_ the "port" is perfectly achievable without LLMs. Zig transpiles to C, then C2Rust would do the rest

Nobody knows if it is less safe than the Zig version because nobody has ever read the code. Maintainers included

When I see something tagged as "AI generated" (as it does in this webpage at the top), I find valuable and interesting to know which AI was behind it. Bun being anthropic, curious to what they have access to and what they used for this. I assumed Mythos or Opus 4.7, but I guess could be any other model as well.

I believe in the latest (possibly two latest?) releases of Zig you have the option to build a self hosted compiler.

> I trust them because of their reputation.

Anthropic has a serious savior complex (when it is actually about total control) and believe that you should not run your own models locally and they do not care about you and I.

This Bun Zig to Rust rewrite is great content for them and for their IPO prospectus, but it isn't performative in the sense that it is fake. (It is real with terrible code.)

What this really means is that it gives the green light to managers and everyone else to use Claude to do massive rewrites; even when it produces hundreds of thousands of lines of slop.

Unless comprehension debt is what you want.

You do not have the same amount of token-spend as the Bun team does.

They will do the "right thing" for their investors (and soon Wall Street).
