There is a growing concern about the technology that brought back Tupac to the stage at a concert recently. No, Tupac didn't rise from the dead, although there are many reasons he would do so if he could. This was a computer generated Tupac. Yes, it is the descendant of the T-Rex from Jurassic Park ...but with more bite.
This is disturbing because of two things. First, now that we can have live action holograms, it won't be long before it moves from the stage to the big screen. I mean movies. Hologram actors acting with live ones. It's a director's wet dream. Producers are outright in delirium. Imagine bringing back Cary Grant to act with ... Justin Beiber. Second, since actors can continue to act even after they are dead, we might as well etch the Oscar for best Actress with Meryl Streep's name.
