Yeah maybe it's a grass-is-greener situation, but from a quick look at SwiftUI and Jetpack Compose, they both seem to have a lot more in common with React than HTML/CSS itself. They seem to encourage functional UI that combines state management, event handling, and view layout. They have primitives like `Text`, `Row`, `Column`, `Spacer`, etc.

I do think the web is a lot easier to learn and the on-ramp is so much faster compared to older mobile UI frameworks, so it makes sense that they're sort of evolving toward the same patterns.
