2. Reduction
3. Simplicity
4. Occam's razor
5. Crazy enough (necessary condition for any new theory)
There's much more to be said, but not here, sorry.
EDIT: whoever wants to discuss the idea further, please send me a personal message to resource0x at gmail. I was thinking on this idea for quite a while, pretty sure it makes much more sense than "emergence" and other mystic voodoo.
After all you can cook up multiple self-consistent ideas of how a machine works in your imagination, but until you actually examine the machine you can't say that your idea actually explains how it works. It's a way it might work.
Usually you want to have at least some cursory observation to form a hypothesis, but admittedly it's inherently very difficult to observe something like the nature of how you are able to observe things. That's why I'm so hesitant to believe anyone who says they have objective knowledge about it.
