Now I'll finally be able to touch Tupac when he performs! Woohoo! Science is a beautiful thing. Which actually leads me to the thought of if we already discovered immortality? Using the tupac example, sure is physical body is dead, but his mark on history and the music genre will certainly never dissipate, and his name will live on far longer than he has; so in this sense he is immortal. And now with the hologram, and this invention, its like he never died. We just need AI to populate to it :)
People started being immortal the moment the digital age started. With proper database maintenance and archiving, nothing short of an Armageddon will kill the people we deem worth preserving. Now, the question is how are we going to make ALL of someone immortal (body AND complete mind, and not fragments of mind only)
