First of all, there is this research - I'm not a neurophysiologist - but you've probably all heard this research that you actually make desicions before your conscious ego is aware that the decision has been made, that there's a slight timelag. So when you think you're making certain kinds of decisions, brainwave study shows it's already a done deal. But time is set by the cycle speed of the hardware you're running on. You know, the human body, we can argue about this cause it's different parts, but roughly runs at about a 100 hertz. Very slow. Well, if there is any meaning to the phrase "upload a human being into circuitry" - a lot of Greg Egan's fiction is based around the idea that you can copy yourself into a machine, you can turn yourself into software. But that when you enter the machine environment that's running at a thousand megahertz per second, you perceive that as vast amounts of time. In other words, all time is, is how much change you can pack into a second. If a second seems to last a thousand years, then ten seconds is ten thousand years.
One could imagine a technology just in a science fiction mood, where they would come to you in your hospital bed and say: "You have five minutes of life left. Would you like to die, or would you like the five minutes to be stretched to a 150,000 years by prosthetic and technical means? You're still going to die in five minutes, but you will be able to leave your elephants over the alps and write the plays of Shakespeare and conquer the new world and still have plenty of time on your hands. In other words, time is going to become a very plastic medium.
- GUESS WHOOO?
