I can think of several approaches that don't involve a desktop. For instance the first approach is to set your super-advanced phone in a (wireless charging) cradle while wearing the appropriate VR/AR gear standing in front of said phone and manipulate your video editing or similar task in VR space. Voice commands as appropriate. Gear and phone connected via super-fast Bluetooth and/or 5G or much better.
The second approach is the phone connected to your touch-screen wall mounted (huge) display. Direct-neural interface is a remote third possibility, at least in the near term. Speaking for myself, I like the latter but that's due to the fact that in a few years, I'm going to be a total shut-in on a respirator (service connected injury from hell). I really want to see the first approach, but that's due to it making computer aided engineering of all sorts a dream.
