I really agree. I described the current state. As my next comment explain it more, there is room for improvements. Is the "write once run everywhere" paradigm a realistic goal, would it be achieved at runtime or at code generation/compilation, without an unbearable cost for users ? I want to believe.

W3C made it possible for web.

A part of me sees react-native adding another option here - "write once, tailor anywhere"

While it's always been possible to have common core logic and then tweak your frontend for each platform as a separate project to get a slightly closer to actual native experience, react-native makes it significantly easier to do so and I think it's that one+ standard deviation away ease that makes all the difference.

I don't think we'll see a lot of successful react-native cross platform that goes for the one-size-fits-all approach but rather, with the same (probably even less) effort, we'll see react-native apps that target the UX of a platform rather than just the UI elements.

W3C provided what might be akin to C compiler standards which are only partly followed by implementors.

The rest is handled by libraries/frameworks/polyfills that get you 80% of the way there.
