Yeah this is the most uncomfortable opinion I see with rust. In general rust doesn't seem terribly well suited to existing toolkits (as most make heavy use of the OO paradigm). What's left is often very immature (e.g. cursive) and so there tends to be a knee-jerk reaction of: let's build a GUI toolkit on top of Servo. Electron isn't just bad because it's all a mess of javascript, it's bad because it's not portable, because the resulting apps are bloated and non-performant, and because they never quite work like native apps.

For all the people who wave the "one true Scotsman" flag at people whinging about the non-native feel of Electron I'd just like to point at Visual Studio Code. Opening a file vs directory on Windows is a hilarious exercise in fermented emacs-like keystrokes. On a Mac, try using the "Window" menu (it doesn't list the children) or try using the minimized window icons (they all have the very useful title "Code").

I think a better analogy would be something backend. Front ends may have gotten slow but that has been exacerbated by intel sitting on 4 core consumer chips for a decade now. However, AMD finally came along and shook that up with threadripper and now you can get 8 times the number of cores from AMD, or 50% more from intel. I think we still have quite a ways to go on the consumer side.
