From what I saw Cosmic has a lot of potential and looks pretty sleek too, right now I’m using KDE it’s a great desktop, but now that I have a second monitor it randomly crashes on me, I think I’ll switch to Cosmic when it reaches beta.
And developers who get familiar and easy tools such as cargo, rust-analyzer and all the popular libraries working in any Cosmic project in about five minutes. And the compiler will tell you if you managed to make memory errors or data races in a very clear way. Always the same way.
You learn Rust and its tools once, and you can just jump into any of these projects and be productive.
And yes, scripting language is needed for Cosmic at some point. There are a ton of them, from RHAI to different lisps to python to javascript. Plug and play, and the interop is easy and fast.
