I say this as someone who cut their teeth on and loves Python for a thousand reasons, I have to agree. Python projects are abysmal. Rye and UV are promising (and I am very excited about them), but they aren't quite ready yet.

"Written in Rust" carries with it significant promises that only Go also has. (Go has a lot of the same promises, for having good tooling and the same mostly-statically-compiled philosophy.)

"Written in Rust" tells me a project is easy to install and easy to hack on. I am far less interested in using non-Rust projects, and I am definitely disinterested in making code contributions to non-Rust projects.

Case in point: It took me much longer to write this comment than it took to install and use marmite.
