Re: What are we actually discussing about?
> What we call 'reality'
There is the "personal reality", which is quite simple but eminently different from person to person, often even contradictory. And there is the "physical world reality" which is huge and terribly complicated, very intelligent scientists are spending their whole lives in an attempt to grasp even tiny aspects of it.
We easily could model the first kind, although one would wonder why bother. The second kind is waaay beyond our capacity to understand, and thus to emulate. We have good notions how specific and limited aspects of it might work, but that's about all.
