<div class="gmail_quote">Quote:<br>Another point I’ve made in the past is that as everyone becomes<br>uploads and accelerates their thinking speeds, space will begin to<br>seem very far away. Right now, Luna is 3-4 days away. To beings whose<br>
brains are made up of molecular computers with 100 GHz switching<br>speeds, Luna is about 3,000,000,000 days away. That’s about eight<br>million years. An eight million year trip to go to an empty wasteland<br>without any art, culture, or much Kolmogorov complexity to speak of<br>
beyond geological and mineral patterns?</div>
<div class="gmail_quote">The near-term future of humanity is to convert the Earth into a<br>“computronium globe” with a web of trillions of simulated worlds<br>within it. In several subjective millennia, we may consume the Moon,<br>
but it will be subjective millions of years beyond that until we<br>colonize Mars. In many billions of years, we may be fortunate enough<br>to consume the Sun.<br>---------------------------------</div>

<div class="gmail_quote">Richard Loosemore replied:</div>
<div class="gmail_quote">I hear the argument, but I don't feel compelled to buy it.</div>
<div class="gmail_quote">For this (main) reason. If we had the power to speed up our consciousness to such an extent that one day RealTime became a million days VirtualTime, we would run the risk of becoming bored if we simply spent all that VT as a continuous consciousness. Much more likely, we would choose to establish a system of periodic rebirths, involving the archival storage of the current set of life experiences and the beginning of a new life in which we could experience everything as if for the first time.</div>
<div class="gmail_quote">In that case, the million days VT would probably consist of several lifetimes.</div>
<div class="gmail_quote">Moreover, people would not necessarily want to experience all of their lifetimes at VT speed, but would sometimes want to come back down to normal speed. And in fact, the lifetimes could, of course, be interleaved, so that several lives were being experienced at once, all at different speeds, but in packets.</div>
<div class="gmail_quote">And (finally) one aspect of this would be the possibility to set up interstellar trips in which the consciousness was suspended for the duration. Or, where many different lives were led during the trip, but all within computronium VWorlds. That way, a community could go to the stars, arrive there with the subjective experience of having only just left, and then explore the remote worlds before going on to the next star.</div>
<div class="gmail_quote">Some of us, I have got to say, would *still* be interested in what Nature, by herself, decided to do at all of those other star systems, and would not want to simply sit at home pretending to live in imagined worlds!</div>
<div class="gmail_quote"> </div>
<div class="gmail_quote">Conclusion: I don't see any *necessary* force to to the argument that this is an explanation for the Fermi Paradox.</div>

<div class="gmail_quote">Richard, very well said!!! I am so tired of the "humanity uploading and retreating into virtual worlds/forgetting about space exploration and colonization" argument. You did an excellent job of dismantling it.</div>
