A simulation would be a sort of intentional dream. Watt’s explanation is one I like. If you could dream anything you wanted you would likely make every fantasy come true, but this would become inevitably boring, even if it took a million years of dreaming. Eventually you would introduce an unknowable element for some change, some unpredictability. After thousands of dreams and continually introducing elements you couldn’t control to keep it interesting you would eventually arrive where we are now. Zero control and a complete lack of remembrance of how you got here. If this is a sim, there were likely many before this that would more closely align to what you think you would want, I’m sure you tried them already though and been intolerably bored by them over eons of replay.
