I wasn't sure whether to post this here or in the 'Technology/Internet' section. I decided it should go here, because in my view the concept is, ultimately, about redemption and salvation for those who proclaim they do not believe there is anything more to reality than what we can see (i.e. materialistic atheists).
According to those who like to preach about it (ex. Nick Bostrom, Elon Musk, Neil deGrasse Tyson), our reality isn't what it appears to be. It is nothing more than a highly sophisticated computer programme, a more highly developed version of 'The Sims', but in all honesty there really isn't much actual evidence for the idea. Science is founded upon certain assumptions, philosophical beliefs that are accepted as given (ex. the reality of the past, the existence of objective reality, the belief that reality is explicable), and in order for it to even work as it does requires there be physical evidence for whatever hypothesis one wishes to test. For the Simulation Hypothesis there is at this time no evidence that could be considered to be decisive, or even convincing. The double-slit experiment, whilst intriguing, isn't definitive, because there is at least one other interpretation out there (the Copenhagen Interpretation) that could account for what is observed.
Here's how I see it. Our reality is as it appears to be, and isn't fake. The simulation idea simply raises far too many awkward questions that do not arise when one assumes our reality to be real. Applying Ockham's Razor, the notion that there is a higher level of reality above and beyond ours that is responsible for what happens in our universe is rather inelegant, and of the two explanations the belief that what we see is real involves the consideration of far fewer unjustified assumptions, and awkward questions are avoided altogether.
1) If we are being simulated by an intelligence beyond our reality, what is the purpose of the recreation?
2) The world of the simulator(s) - is that real, or is it fake too? If their reality is a simulation as well, then there are others who control their reality, but then the same question needs to be asked about the simulators of the simulators, and so on. An infinite regress is what one winds up with, which ultimately explains nothing.
Anyway, this is my very first "myTake", so I hope I did this right. I don't believe we are living in a simulation. That's just silly. (Note: the image below is just there because for some reason I cannot post this without one)
