Here is the 'plan' as outlined to me by an old dust hippie outside of Gerlach (Warning: totally crap, light speed remains the limiter, but entertaining still the same):
>Humans figure out this brain and AI thing sometime in the next 200 years. So, now 'you' don't need a body or any of that jazz anymore. Brain uploads, that whole shebang, fun times ensue, maybe
>Great, now we start ctrl+C and ctrl+V'ing ourselves a lot, we start getting into the real nitty gritty of physics, chem, bio, math, etc. We get limited by the amount of computers, matter, and energy we can muster. The Earth turns to computronium and heat.
>You know how this ends: We deconstruct the Earth and solar system, send the sun into brown dwarf state and 'colonize' other systems to do the same. The issue is still light speed. More computation is great, but it is the flops that matter. This means that other systems are effectively useless and on their own as it still takes centuries to distribute the computations. You need more plain-jane matter and energy. Bigger systems are primo then. If we go to interstellar war, it will be over very large systems. Still, it's unlikely because...
>Black holes. You fall into one, and time slows down. Boom! You have more flops for no effort. All you have to do is fall into one and have your 'puters on the outside do all the work faster. We super-engineer some craziness and make tiny ones to orbit about. (Note: Now things REALLY fall off into dust hippie-land).
>Cosmic eggs. The black hole is the egg and we are the sperm (yes, this is nutto but fun). We all merge our individual black holes and then we make the 'great journey' to the center of galaxy to all merge with all the other AIs out there. He said it was the only real option. The horizon of the super massive one in the center is the 'flattest' and therefore easiest to orbit and 'choose your time dilation' (I think he meant that it had the smoothest gradient as it was the biggest).
>We are then the first to be intelligent. Dust Hippie then said something that, by this super crazy funland logic, was pretty good. Assuming these time dilation and systems turned into computronium ideas kinda hold water, then we know there are no other super-AIs in the galactic core. This is because we can see many massive suns in very odd orbits about the galactic super black hole. If they were there, went his thinking, then they would set them in better orbits with a constant 'power feed' into the AIs orbiting closely to the black-hole, also they would not be visible to us as they would be enshrouded themselves by computronium, with no radiation wasted on the way out. Not a bad extension of crazy logic, I'd say.
Now, these are all predicated on our current physics know-how and that light speed is as slow as it is. We have great suspicions that this is not true, as our form of matter is ~5% of the total mass-energy budget of the universe and it seems most of the universe is not 'positive' energy (the universe is accelerating in its expansion). Still, its a fun, if likely LSD fueled, theory.
