There is a certain arrogance in thinking that, of the entire timescale of the Universe, one happens to be living at the precise point in time where one saw the rise of the personal computer. What are the odds that one happens to be born at a time when civilizations start to create simulations of reality: videogames, virtual reality, and so on.
I’m worried that the simulation hypothesis seems to be framed by concepts provided by computer science, itself a very recent field, rather than from first principles. Has Socrates, Thomas Aquinas, or Descartes ever proposed reality as a simulation? I think part of what explains the popularity of the simulation theory is that STEM has misplaced the humanities, and so the concepts and ideas from philosophy and history are not there at all, leading to solipsistic or self-referencing questions like the simulation hypothesis.
