Nothing. You can always vibe-code in Rust even when the rust-lang/rust repository itself largely forbids vibe coding.

But one of the reasons they switched was because the compiler upstream for the original language they used, Zig, wouldn't accept slop contributions they wanted to make for Bun perf. What will they do when they need to try to push a slop contribution upstream to rust?

At this point they will probably just fork yet again and maintain some vibe compiler.

		Is there a citation for this? This was my suspicion but it's quite amazing if this was the actual reason for the bun spectacle

		They should make FullstackLang. It compiles English in .md to machine code that can directly run on the specialized hardware it designs for it that you have to 3d print at runtime. Every program gets its own custom hardware. Composability and reuse be damned. Pay the token masters for every thought you have

		Huh. I wonder if the original intent was to merge an AI generated PR to a high-profile project like Zig. It makes the headlines and generates hype. But that went embarassingly bad for them so they had "port Bun to Rust" as a backup.
