I'm a student, and all we get taught is .NET/JFX/Swing. It's really hard to learn modern stuff (MVVM...) because the complexity comes from problems we've never had, so it's hard to relate.
Compose is incredibly better than XML, but it still needs a proper application architecture, and that's not something you can find good tutorials on
Also it's really nice to see the days coming where we could have a truly Multiplattorm application with everything shared
