This is the weird elitist argument again. I've done my share of native UI development, and it's total pain compared to HTML/CSS/JS. The tools are crap, the compile cycles too long, the languages to restrictive, the APIs too ad-hoc, the layout engines too crappy, the technology support (eg. multimedia) lagging too many years etc etc.

The native libraries had decades to fix this mess, yet they're still by and large the same as decades ago. Will not miss them.
