Video phones that were commonplace in sci-fi for years have made their way into the real world in the form of FaceTime and Skype, so kudos to developers for proving that the future is now. Unfortunately, people will never be satisfied with what they have — have so get to the “Star Wars” Holograms already.
The technology exists, but not in a practical sense. Tupac was "resurrected" as a hologram, and election news was delivered by hologram on CNN for some reason. However, all of these instances were prerecorded; real-time holographic interaction would bring people closer together. If it's good enough for The Emperor, it's good enough for you.
