NPM and pip hell come about for several reasons, one of the biggest being that package versions are global. In rust, you can project A can use dependencies B and C which can both depend on different versions of D. Cargo/crates generally also solve some of the other metadata problems Python has. This means the developer experience is _significantly_ improved, at a potential cost of larger binaries. In practice, projects seem to have sufficiently liberal bounds that duplication isn't an issue.
