&gt; So web apps can&#x27;t have reusable components now?<p>I&#x27;m not saying they can&#x27;t, I&#x27;m saying they don&#x27;t. You go ahead and try to fix that, create widget#772981 that still won&#x27;t support typed-selection, or will break with large text or what not... I&#x27;ve seen too many of those, most of them bad, and none of them standard. So far, React is the only thing that even comes close to a sane model for a contender to UI development on the desktop, and it still mostly fails the accessibility checkbox.<p>&gt; WebAssembly will take over for web apps eventually.<p>More eventualism. Do you have evidence for that? Do you even have evidence that it&#x27;ll be better than what we have now in other languages if it does take over?<p>&gt; UX knowledge isn&#x27;t toolkit dependent<p>A lot of it is. You&#x27;d be surprised just <i>how much</i> UX is crammed into Qt Widgets for example. Years of experience making them more accessible, more usable, more consistent with the platform they&#x27;re running on, etc.
