What we experience is not the physical world but a simulation of it
by our brain. So, even if we assume that there exists a "primary"
physical world, we're not really living in one, we're at most living
in a World that's simulated inside it.
The fact that our primary experiences derive from a simulation
allows magicians to earn a living. If you walk into your living
room, what you see, what you experience is not the living room as it
exists right now, it is almost entirely a reconstruction based on
cached data from your memory.
Real time processing of data would be computationally infeasible,
and we need to keep in mind that the brain evolved from a simple
nervous system. In each step in the evolution where this became more
complex, there would never be a system that could render a precise
picture of the World, it was only ever about getting to a better
response giving the inputs. And in principle all inputs from now and
some time ago can contain useful information.
Yes. That is made explicit in Turing's paper, and that is what
eventually convinced Gödel of Church's thesis.
So, this way we ended up with a brain that ends up simulating the
World,
Not the World, but some part of it. OK.
the simulation is what we are (the set of everything we experience
is an OM that defines us).
Very locally, and the OM makes sense only to a Universal machine, and
unfortunately, to an infinity of universal machine distributed in
arithmetic (or any semantic of a Turing universal system), and that is
why at some point we must define the observable by a statistics on the
couples (universal machine --- OM), i.e. the computations.
