Thanks for the elaborate reply! All my backend stuff is in Python (Django) but I think there is python WASM frontend stuff too so I think quite some of your insights might apply. Python is not quite as secure-by-design (secure as in I know for sure how my code behaves and where to expect exceptions) as rust but still better than JavaScript so I might look into that!

Why do you prefer WASM over JavaScript (which is suppose is your alternative for the UI work)? I build a lot of web stuff but haven't tried WASM yet.
