> The C/S architecture of X11 hits the spot when terminals and thin client are the norm, that means 20-30 years ago, but today, we all have dedicated graphics display devices (GPU, monitors) even in our pocket smartphone, and the way X11 works is holding Linux desktop scene back.

I used X11 forwarding just yesterday to open & control my linux desktop's music player from my mac - which other 2020 technology allows me to just run

    $ ssh -Y my_desktop
    > my_music_player&

and being able to do that without lag (scrolling through the list views was much more fluid that my experiences with e.g. RDP or VNC even though it's a Qt 5 app, strawberry, which likely does most of the drawing server-side) or blurry jpeg-compressed pixmaps, and with the ability to resize, minimize, etc this individual window without any issue ?
