I could see the hologram industry forthcoming back in the late 1990's and spoke to a few, including a chip designer at Intel, about my ideas of hologram performers at nightclubs, concert halls and even in people's living rooms. This new technology has really been around a while, we've seen hints of its emergence at Disneyland ghost rides, but computers take it to a whole new level. The chip designer told me that computers didn't have the power back then to do the things they're doing today.
Hologram technology is the wave of the future and a new means of life-after-death revenue for people after they're gone ensuring they're memory lives on and doesn't go stale. A hologram imprint would be difficult to duplicate, so the work's copyright safe. Hologram computer programmers and producers will certainly be in great demand.
"For 78 minutes I was dead and, even if I lived, was expected to have suffered brain damage," Muamba said. "But I'm very much alive and sitting here talking now. Someone up there was watching over me."

"I felt very slightly dizzy. It wasn't normal dizziness -- it was a kind of surreal feeling, like I was running along inside someone else's body," Muamba said. "I had no pain whatsoever. No clutching at my chest or tightness like you see when people have heart attacks in movies. Just an odd feeling that's impossible to explain. Then I started to see double. It was almost like a dream.
"I could see Spurs players running around in the distance and saw two Scott Parkers and two Luka Modrics. That was when I realized something was seriously wrong." Fabrice Muamba: I felt 'no pain' - ESPN.com
I predict the new trend will be bringing people back to life, raising the dead in one form or another.
