Clarifying my comment, if I was to create (say) a tool today to monitor my network, with graphical charts, push buttons, etc., it's almost inconceivable that I would choose to write it using an X toolkit of some kind, even if it were only meant to run on Linux desktops. Instead, I would toss up a web server and write the front end using web toolkits, etc. I think a lot of others would too, and in that sense, desktop app development is being overrun by the web (plus Javascript, DOM, CSS, etc.) It's true that web browsers have to run on something, but on some platforms, that something looks a lot more like bare metal. I think it's conceivable that X and Wayland will head into the sunset as tech like emacs has. That doesn't mean I don't like them--I do--but realistically their future is unclear.
