Like 5 years ago I worked at a digital agency that received a bunch of devices from different manufacturers. AR, VR, spatial audio, directional audio, holographic displays and were given a sort of blank check to make some cool experiences. We never really got past the novelty factor. Obviously there may be some cleverer folk in the world than we had at the time, but I came away thinking these would never really get mainstream acceptance for anything besides gaming. I also came away realizing that mouse and keyboard are really just amazingly efficient and 2d screens are perfectly fine.
