their saying we'll have virtual realities the likes of the matrix in less than 40 years, dunno bout the whole enslavement thing where AI has taken over the world, but maybe somthing more on the lines of the TV show caprica, that being the case, not just the sky, but anything we want our world to be would be the limit... and also that being the case, u could live 30 years of memories in just a few seconds if you could just download them into ur brain, so you could technically relive the whole war, and have it feel like the whole 7 years of it, but only a few seconds of real time has gone by, and then if u dies, lets hope u just get disconnected
just don't forget
moore's law... thats all i can say
