I have often used the comparison to early personal computers. The things were mainly switched and lights, but there was potential for where it could go.
I heard that even early Apple people would say "A computer in every household", and people would ask, "What would I do with a computer?" and their best answer was "It's a great way to store and file your recipes."
I love holograms, always found it extremely fascinating, but this is not really an argument. Anything _could_ sort of become the next personal computer, the question is why you think specifically holograms are useful?
I feel like anywhere you see a flat 2D image could be a 3D hologram eventually. And holograms give the "whole message", so more information, better information, clearer information. That's the potential. So portraits, some day hologram cameras, CAD output, advertising, and yes eventually hologram television/displays.
But we are starting with something more simple, and not trying to promise everything to everyone. That does mean looking for initial use cases that will take off early.
I certainly hope you’re right, I want to see holographic displays replace lcd for one thing, even though I’m a bit skeptical.
3d tv flopped, it could have been a start of something, terrible as it was. Lightfield cameras didn’t take off either, maybe because of the price. Let’s hope this could be a beginning!
