my thought exactly. There's no way processor speed can continue at its current pace to that point. It would have to be nearly infinately fast to simulate all the 10000000000000000000000000000000000's of atoms i can see right now, and even put an electron microscope up to and see formations of. There's just too much to simulate, that is, of course judging that this person is saying that WE will be able to do it eventually. I don't doubt that it's possible that processors are a lot faster beyond the matri
Well, you see, the funny thing is that you don't need to simulate the atoms at all. All that you need to simulate visually is the smallest object a person can resolve with his unadied eyes. Everything else is simply mapped on top of that.
For touch, you just simulate the smallest texture difference that a human can feel. For sound, all you need to do is simulate the sounds that a human can hear.
All of these would need to have a certain safely margin to account for people whose senses are better than oth
Uh, what if someone builds a device to look at smaller objects than the unaided eye can see?
There are so many ways to do that, that it might conceivably be better to simulate at a lower level than to deal with all the possible special cases, or allow people to detect the flaws.
As for processing limitations, it's might not be impossible if you can underclock the minds of participants - put them in suspended animation or something.
High level emulation. If there is a microscope for you to look through, it is being emulated, then whatever has created the microscope can program it to rewrite everything you look at with it in a way that makes sense to your species.
it would be mind-numbing to write (much less RUN) a program that would fully emulate every atom in the world at all times. all you have to do (ask anyone in movies) is emulate the minumum amount to look realistic on screen. if someone needs to look closer, emulate what they're examining properly, only while they are examining it. Otherwise you can very easily emulate a white box with bumpmaps, rather than the wood, the drywall, the paint, the electricity, and everything else that makes a wall. until someone examines the wall, you can get away with just a white box with paint-like bumpmapping.

On the Summer Reading List thread, many slashdotters mentioned The Metamorphosis of Prime Intellect. Within Ch. 6 was a description of how Prime Intellect "rewrote" the Universe, as follows:
"No, you wouldn't. Let me ask you something. If I leave here...if I go back to civilization...does this forest continue to exist?"
"I can leave it running in your absence if you want." Caroline wanted to throw up. Now even the forest wasn't real. Nothing was real. "Don't bother. Get rid of it." Instantly, it disappeared. She was standing in an antiseptically white space so pure and seamless and bright that the eye balked at reporting it to the brain. She was standing on a hard, smooth surface, but it was not visible. There were no shadows. There was no horizon; the floor and the sky looked exactly the same, and there was no transition from one to the other. She might have been standing on the inside of some enormous white ball. Prime Intellect was still there. "What is this?" she asked. "Neutral reality," Prime Intellect said. "The minimum landscape which supports human existence. Actually, not quite the minimum. I could get rid of the floor. But that would have startled you."
So basically, the visual portion of this world would just be like a raytracer running constantly. Whatever the eye can see it simulates and draws; out of the eye, nothing is (and need to be) simulated.
