It is in use in many specialized applications, but it is very
difficult to use for 3D TV and such. It demands orders of magnitude
more resolution in order to get out a decent image, and it is hard to
build a device that can display holograms in real time (so far as I
know, none exist).

Holograms don't generally look convincingly like the originals, and I
know of no "True Color" holography processes.

Yeah, but we don't know how to do it.

Well, again, as I've mentioned, the problem here is engineering
vs. breakthroughs. Spreading the internet to every piece of the planet
or getting a 2Mbps radio link to your eyeglasses is purely an
engineering issue -- hard problems, but no breakthroughs. We don't
know HOW to grow steak in a vat, so it isn't an obvious near-term
thing.
