I dont know much about this Tupac dude other than that he was famous and died, and then yesterday a hologram was represented of him somewhat convincingly at a public performance on a stage. It makes me reflect that, of my superset of all friends, 99% of them I have not talked to in years, and they could very well be dead. A few actually <i>are</i> and I found out only recently. To suppose there eventually will be a way of programming the states of our personality into some agent, and let others interact with it, I might say this surrogate might be enough to trick my brain that they are still alive. What if facebook could ask you 1500 questions, and emulate the first 80% of your psyche? It would be a weird way to remember someone, chatting with their agent like that. Like that mastergeek at the end of Serenity, perhaps. Some limited interaction thing. It's all damned weird to think about. I am uncomfortable with this thought experiment so far.
