Infinitely large virtual monitors will be useful, since programming usually requires a large amount of context. But that'll probably work better with AR goggles so that you can actually have some real world context for your input devices. Because you'll still be using a keyboard, and probably a mouse, because waving your hands around in the air and talking to the computer are always going to be slower and less precise.

And, no, I don't want to throw my functions in a pile on the ground and sort through them.

There are also very simple usecases: Graphics tablets with screens are pretty expensive (Wacom). With AR it would be possible to simply use a bigger and cheaper one without a screen.
