The 3d demos are similar to what you experience when using a VR headset with desktop emulation software. I ran experiments with that for several months and while the concepts were interesting, context switching in a simulated physical space was actually a lot slower than alt+tabbing between things.

I use virtual desktops, where each desktop contains a single thing that I am working on, and everything related to it. Then any good window manager can switch between them quickly and even give you a spatial sense of where you are. I organize them as a priority stack, so the topmost priority is in top position and then it goes downward from there

There's a lot that this "campus" product does that isn't present in such a set up (multi user, zooming, etc...) but virtual desktops give you a lot of the benefit and come built in to most of our operating systems

They mostly do not gain a lot of users. Good luck!
