My argument basically comes down to the alternatives. Have you tried them? Native iOS development was a nightmare without deep mobile expertise until React Native and the like came about. Windows/Linux/Mac cross-platform apps were in the same place before Electron. IT's far from perfect, but ask anyone today what they'd prefer to build an interface with and it's most like HTML/CSS. Especially for highly graphic intensive, responsive layouts, there's almost no competition really.

Doing things well requires expertise.

Seriously?! Qt predates Electron and is a far superior solution. Of course, if you only know web development, your existing knowledge doesn't translate over easily, but the reverse is equally true.

Only if they are already experienced in web development. Otherwise, Qt Quick is much better, taking the positives from CSS, without the downsides of using a document format to layout a UI.

Seriously, Qt Quick is far better. Though on the desktop, you'd be better off not building a "highly graphic intensive, responsive layout" and instead adhering to the established norms.

Well, I think it would be pretty easy to take the best ideas from HTML/CSS and make something MUCH MUCH better that would be completely incompatible with these- See for instance subform (https://medium.com/subform) The problem with this of course is that these alternative systems aren't widely supported, but at some point I expect one of the AFGAMs to publish and push one of these alternate layout systems and attempt to get higher adoption.
