The problem with Electron is that business-wise it is an excellent decision. You can get by with a few people to wrap the web app and integrate it with the OS, and then get updates pretty much for free.

Yet for the user it is bad -- bloated, slow, feels non-native, has specific bugs which are hard to address for the devs, etc.

I don't see any light for the desktop UI development unless there is some lightweight universal rendering engine. Tauri with WebView is somewhat promising, but it has problems on Linux and it is hard to target older systems.
