Now: I ski down a mountain; eyes signal steep cliff ahead; brain concludes: possibly more than I can handle sends signal to adrenal glands; defenses get fired up heartbeat increases, reaction times reduces; I am getting an incredible turn-on; I feel competent and powerful. Admittedly all these signals of cause and effect are processed through the brain and can conceivably be simulated there. But... ...Later (IMHO and here I need some input): I lie in my cyber-bed or whatever will equate for a position of comfort then. I send a signal to my cyber-brain: Get me to the edge of systems breakdown (with a specified safety margin of course) and convey to me all the sensations of exhilaration and joy. Somehow this does not seem quite the same. >An uploaded human will be as much like a computer of today as a human is >like a paramecium.

I hope you are right, but somehow I cannot imagine a state machine, which will clearly include all the advances of today's technology, timid as they may seem by the standards of the day, to contain or even tolerate the uncertainties and ficklenesses of the human brain. >Now, once uploading is accomplished, I'm sure there will be some folks who >will start tinkering with their brains, trying to enhance intelligence, >surpress instincts, etc. But I won't be one of them, and you won't either >if you don't want to be. I like the SF concept of computer link to bio-brain to allow retrieval from an information library, but 'uploading' would suggest to me an integration of the two. Where do 'I' stop, and where does the rest of the world start?

Because we would have no doubt the capability of that chess computer (Deep Blue?) to evaluate probable results of any action we take to n extensions. Spontaneity would be replaced by prior evaluation. The result would be a high degree of risk avoidance, which would result from knowledge of the likely result prior to taking any action. >What do we know now that would preclude >life as an upload being *more* exciting, not less exciting than it is >now, in a meat body?

Maybe I am more concerned with the physical aspects of living and less with the cerebral, but I can just not see how the power of pre-evaluation of actions can lead to more excitement in real 'life'. With simulations it is different. They are a game and any pre-evaluation of actions could be suspended for the duration, since any harm is unlikely.
