HTML layout and rendering is almost never as fast as GUIs like Qt. Also Electron apps usually use JavaScript which is slower than "fast" languages like C++/Rust/Kotlin/etc.

The reason people use Electron is because it's easy, especially if you have to have a website anyway. Slack is a great example of this. They already have a full website so it's kind of silly to redo the whole thing...

Unless AI makes it easy. We'll see I guess.
