Consistent UI and control. I re-wrote my electron app in Swift. Its great. But... some of the UI is weird at times; weird patterns; weird behavior. And Apple's UI framework is one of the better ones. Even for AI, each platform will have its own quirks and just _finding_ them takes real users to expose. We take it for granted how flexible and powerful browser UI is, because there's so much baggage and performance related factors. But many UI frameworks are worse, and historically always were.

I think what we're seeing here - and likely to continue to see - is new versions of web UI that eschew a lot of the historical baggage given they don't need to support older websites. And possibly something more powerful. So I guess re-writes or partial ports that take only the parts we need. Presumably a bunch of people will try and hopefully, a few succeed.
