Electron is pretty capable technology. SpaceX uses Electron in space. I recently reverse-engineered firmware of some small device with tiny screen and underpowered CPU. It used Electron for its GUI.

I would say that issue is not Electron itself. Issue is other GUI frameworks which are so terrible that developers prefer Electron despite its objective issues.

I spent good amount of time learning WinAPI, learning MFC, learning Delphi, learning Swing, learning JavaFX, learning a little bit of WinForms. I wrote few native Android apps and iOS apps. I'm not an expert, but I saw enough APIs.

I'm mostly backend developer. I know JS, but only enough to be able to read the code and do some modifications.

If I would need to write GUI, I'd write it with HTML/CSS/JS any day. It's infinitely easier than whatever native tech there is.

I did not try Flutter or SwiftUI though. Those are most modern frameworks, may be they improved.
