By the way I wonder what would happen if such neural-interface existed. What social changes could it produce - when there was no social segregation, everybody could be wise and creative. What world would it be, full of geniuses? Would they create a new advenced technologies that could help spreading our species all over the universe? If so, what would happen if there was no room left for us.. If its really possible that space could end, beacuse when we look at the average life time peroid, this "time" versus space seems to be optimal. Assuming geniuses understand that life can't last forever. Assuming geniuses only interference with death would be creation some kind of alternative virtual reality, like in Gibson's Neuromancer, that could store and remember dying humans... On the other hand, this could produce new social order that could estabilish stable relationship between space and information. If not, there can be real problem with physical space for memory storage of this virtual world. Because information is directly related with energy, and energy is related with mass...

So how we can be sure that we already don't exist in such a virtual world, whatever model it uses. What our life forms are, like not autonomical machines producing, replicating and spreading information? Maybe each one of us is such a virtual world, bigger or smaller, connected to other "physical" machines... Is it possible to increase information storage and transfer efficiency without abandoning current reality model..?

Maybe it's neither energy nor information, but time most important? Maybe information and energy just "exist" like space - everywhere for everyone - but we can access it only for a very short time - our life time peroid - and if so, we are still unable to make use of..

Even if it's all possible, why am I thinking about these things anyway..?
