This is an additional introduction for mind, science, future. First a quote: "Science fiction. You're right, it's crazy. In fact, it's even worse than that, it's nuts. You wanna hear something really nutty? I heard of a couple guys who wanna build something called an airplane, you know you get people to go in, and fly around like birds, it's ridiculous, right? And what about breaking the sound barrier, or rockets to the moon? Atomic energy, or a mission to Mars? Science fiction, right? Look, all I'm asking is for you to just have the tiniest bit of vision. You know, to just sit back for one minute and look at the big picture. To take a chance on something that just might end up being the most profoundly impactful moment for humanity, for the history... of history." - Eleanor Ann Arroway in science fiction movie Contact (1997) People should think the fact that we can actively decide how we will live in the future, by making choices today and realizing the consequences of our decisions. The future doesn't just happen: We create it through our action, or inaction, today. Let's remember what Kenneth H. Olson, President of DEC, Convention of the World Future Society, 1977 said: "There is no reason for any individual to have a computer in his home." And that was in year 1977... So there you see how difficult it is to predict the future! And now at the end of this introduction I really wish you have a nice day, and wonderful future! Enjoy surfing in this virtual world!
