I was using poetry pretty happily before uv came along. I’d probably go back.

Note that uv is fast because — yes, Rust, but also because it doesn’t have to handle a lot of legacy that pip does[1], and some smart language independent design choices.

If uv became unavailable, it’d suck but the world would move on.
