I think revisiting Linux would be great idea, but the current state isn’t that far off from what he experienced few years ago. Wayland protocols aren’t fully there yet, NVIDIA still needs some work, portals, desktops, 3rd party software and hardware support, package formats bullshit… There’s shit load of pending changes still being discussed, progress is being made, and even then, adoption of new solutions will take a while. It only make sense to revisit when there’s huge technological leap. Realistically with how slow things are going sometimes, it may be the end of the decade or close before the landscape looks really different.
