The most surprising part of uv's success to me isn't Rust at all, it's how much speed we "unlocked" just by finally treating Python packaging as a well-specified systems problem instead of a pile of historical accidents. If uv had been written in Go or even highly optimized CPython, but with the same design decisions (PEP 517/518/621/658 focus, HTTP range tricks, aggressive wheel-first strategy, ignoring obviously defensive upper bounds, etc.), I strongly suspect we'd be debating a 1.3× vs 1.5× speedup instead of a 10× headline — but the conversation here keeps collapsing back to "Rust rewrite good/bad." That feels like cargo-culting the toolchain instead of asking the uncomfortable question: why did it take a greenfield project to give Python the package manager behavior people clearly wanted for the last decade?
