I think the idea of 'reality' is some notion of infinite reducibility.
That examination at any scale remains 'system' consistent, or at least not 'system' inconsistent.
I think that imagination operates at a limit of one or a few levels of scaling. At some scale it becomes irreducible or ceases to translate to some
finer or greater scaling. [could infinite reducibility be synthesized with algorithms?]
This simulation/hologram/computer-program while not absolutely impossible, seems nearly impossibly improbable to me.
Our understanding of our 'reality'/universe is information, but that is our tool for dealing with, understanding it.
Enabling relating to it without getting lost in it.
And i think we are projecting our mentality/functional-imagination onto something that is no respecter of those things as far as one can discern.
We want to make the manipulation, fabrication, creation, alteration of reality into some easy, almost effortless action.
But if it were that easy it would lose much [all?] of its meaning. At some point it would disconnect emotionally, which usually is our depth metric of
'meaning'.
Either the Universe/reality is synthetic [uniform, systematic, contrived, created] or it is organic [accidental, no (single?) point of
origin/creation].
Organically would be more fractally, distributed rooting. [distributed load? complex root?]
Synthetic is a creation of either shallow or limited [almost certainly uniform] depth.
Organic is [limited?] unity/organization achieved from scattered, chaotic &/or alternative dimension sourcing.
While the Planck length does give some [incredibly small] discrete limit of functional length in the Universe, because it is so vastly far from even
the upper length scales we can luminously observe, i personally think it might be more of a friction point in which we, our universe[experience?] &/or
something can lodge, get wedged.
It is like a reflection in water or mirror. It creates a visual experience that is indistinguishable to our eyes from our visions of reality. But it
is a phenomenon & not an alternative reality.
A virtual reality would be a sensory phenomenon, but there would be quite limited things one could do there & self examine that realm/domain.
Because a presumed reality would have infinite reducibility, it also confers the capacity to do many things that otherwise could not, would not be
possible in a limited depth domain.
People want things to be easy,
and well, from an older guy,
things just aren't that easy,
least ways not any way i can see.
Maybe an analytic way to look at it is,
if the source of abstraction/unity/organization/structure comes from a fractalized/distributed [chaotic?] foundation, it is probably not a VR type
environment.
If on the other hand the source of abstraction/unity/organization/structure does come from a discrete deterministic source then you could be looking
at some form of potential VR source or at least something that on some level of operation may be reasonably manipulated as such.
We do have [discrete] atoms/particles at some level, but it is so far, so minutely broken down [10^23] and then atomic discretion begins to break down
in Bose-Einstein condensates near absolute zero,
that doesn't seem to qualify as any kind of VR i can relate to.
And sound more like the gentle mercys of an otherwise pretty unforgiving environment/Universe.
While it sounds pleasing on the surface,
It just doesn't compute for me,
so you are going to have to come up with some kind of Amazing evidence to demonstrate to me this is anything other than a chaos rooted organic
accident Universe.
Organized, synthesized, uniformed systems tend to have singular or very fine ranged vulnerabilities.
Organic, natural [systems? does that even apply? experience?] because they arise from both nowhere & everywhere, are probably much more robust.
Reality seems pretty robust to me
It seems to be beyond our worst tampering, . . . so far.
Maybe we should pray the Universe is not that fragile, that vulnerable to malevolent minds or reckless irresponsibility.
