Even if the Simulation Hypothesis is false, you still ‘live’ or ‘exist’ in a virtual reality, thanks to yourself. You ‘exist’ within a virtual reality because all of your external really real reality is alt
red by your own brain’s internal mental software to fit inside your skull. Since really real reality isn’t inside your skull, what you perceive there has to be virtual reality generated by your brain’s mental software.
Video games, training simulations, “what if” research scenarios are all 2-D. Depth is an illusion generated by the software.
Now say you climb up to the Observation Deck of the Empire State Building (or equivalent) and take in all of the vast external landscape spread out before you. Now clearly that volume of space you see cannot fit inside your skull, yet that’s exactly where it is since 100% of your really real reality is literally now inside your skull but as virtual reality. Everything external to your skull is perceived and filtered to fit comfortably inside your skull. Just like in a simulation, the dimensionality is transformed. Left-right and top-bottom are compressed to fit and depth is again illusionary. Your external world maybe 3-D but your perception is 2-D – just like any other virtual reality simulation.
You don’t have enough bits and bytes inside your skull to accommodate all that you see, so short-cut compromises are being made by your brain’s mental software in order to fit what you externally see to fit that view that’s now inside your skull.
I cannot fit inside your head but if you saw me, that’s where I’d be thanks to the photons reflecting off of me and into and through your eye and on to your retina hence converted to electrical impulses which transmit as electrical signals into your brain which reconstructs same back into a virtual reality version of me that now can fit inside your skull.
In reducing the vastness of outside (your skull) to the compactness of inside (your skull), that’s showing an economy of scale. There has to be a loss of data in this compactification of a large amount of volume thrust into a tiny volume (your skull). Lots of stuff gets left out. So in fact there might be relatively little similarity between the really real reality out there and the virtual reality inside your head. It’s like saving one in every ten letters that’s in the text of a book or other document. It’s the same with any simulation. There’s never a one-on-one correlation.
This concept of Games for Virtual Reality is all in the mind is also nicely illustrated by the fact that you dream. Your dreams are internal to you. They are virtual reality. Your brain’s mental software can create highly, very highly realistic dreams and dream scenarios. And as with the case of the translation of a vast external reality shrunk down to fit inside your skull, your dream landscapes are mini versions of what would exist, if they exist at all, ‘out there’.
How about memory? Say one hundred days ago you did one thousand things from waking up and getting dressed, to going to the bathroom and making up the bed, to making, eating and doing (washing) the breakfast dishes, from going to the store to buy milk and bread, to watching this and that show, reading this book chapter, going out dancing, posting bits and pieces here – thousands upon thousands of possibilities. Presumably your neural processes didn’t discriminate between all of these one thousand activities that you did one hundred days ago. Yet one hundred days on, you might remember say just two out of those one thousand things that you did, yet you made no conscious decisions about what to remember and what to forget. So apparently there is a software program within your neural networks that decides for your conscious self what to forget and thus dumps those nine hundred and ninety-eight activities into the recycling bin and deletes it all. So there’s deliberate design that removes any and all unnecessary clutter and deliberate fine-tuning by defining exactly what is and what is not clutter.
Now take the two things you do remember – say one of which was this new catchy tune on the radio. Now you don’t have inside your brain any of the standard technological memory retention devices like hard-drives, USB sticks, LPs, CDs & DVDs, pieces of paper, celluloid film, punch-cards, and so on. So what exactly is storing those two activities from one hundred days ago? It probably has to be chemistry of some sort. Since I can’t think of any kind of known chemistry (atmospheric, nuclear, cooking, blood, soil, organic, inorganic, bio, etc.) that incorporates memory, how is this new catchy tune stored?
Oh, there is one other memory storage device – software.
