Isn't this mainly because of the OS builders? MS, Apple, and Google? The only cross platform GUI system they all support at this point is browser based UIs. And given that developers basically any UI dev practically needs to target the web now, I don't see why this is surprising.
We seem to be blaming developers, but developers are just dealing with an ecosystem where this is the best common denominator. There's another comment in this thread, that points out that Electron is only 5 years old, and there is a lot of opportunity for performance and system utilization improvement.
IMHO if we want this to be better, then the OSes should make this easier and more performant for developers, and by extension, then their platforms will out perform and outsell the others.
