> Maybe the takeaway is that 20% is about all the LLM can muster

At this point there's a long list of projects that have used LLMs to rewrite a system in Rust including:

  - Bun (https://github.com/oven-sh/bun/pull/30412)
  - Valkey (https://github.com/ianm199/valdr)
  - Git (https://github.com/gitbutlerapp/grit)
  - Postgres (https://github.com/malisper/pgrust)

With the exception of Bun, these projects were done pre-fable too, so I bet Fable will make these types of rewrites even easier.

I'm not sure about the other three, but Bun's rewrite from Zig to Rust was a bit of a joke. `unsafe`s in the thousands, a quarter-million lines of diff, and merged inside a week with no significant public discourse (at least, not much that was responded to by the author).

		Still waiting on that blog post from Jarred that will supposedly answer all the questions and concerns about the rust port.

I think the standard should be rewrites that are at least as good as the original, not buggy piles of unfinished unmaintainable crap.
