@thomasfuchs I count at least 5 waves of "stereoscopic 3D is a game changer" innovation going back to the 1850s. Every time so far it evaporates.
My theory is that it's a combination of the wow/novelty factor plus the idea that 3D has to be lots better. Always ignoring that it's cumbersome and that human brains don't need to use two eyes to reconstruct depth.
