There's a bit of a chicken-and-egg thing going on here, though. As a close-by comment noted, there are signs of a convergence of thinking towards "cross-platform means Electron", when this is not actually the case (or is not required to be the case).
To the extent that this is true, it acts as disincentive for people wanting to pursue non-web-dev pathways in their careers, which then further limits the availability of such developers, which then further "confirms" the "cross platform is Electron" idea.
Developing with Qt is (I am told [0]) not much harder than typical web equivalents, but it is different. The result is generally more performant, both in terms of UI and also data handling/computation.
[0] I personally work with GTK, not Qt; Qt goes much further with hand-holding developer helpers than GTK does.
