New realities are imminent: how virtual reality reframes big questions in philosophy.

“(…) Australian philosopher and cognitive scientist David Chalmers considers how VR is reframing and shedding new light on some of philosophy’s most enduring questions about cognition, epistemology and the nature of reality.”

Or, as one of my much smarter colleagues put it (not a quote, just the gist of it): One needs to define the terms reality and simulation first. If the building blocks of our reality are atoms and molecules, of course all what we see or seem could be considered a simulation.
