From a philosophical standpoint, the simulation hypothesis extends an ancient question: what is reality? Philosophers like René Descartes and Bishop Berkeley pondered whether our perceptions could be deceiving us. In modern times, this takes the form of whether consciousness could exist within a digital environment indistinguishable from 'base reality.' Some argue that if a simulated world is rich and consistent enough, it should be considered real in its own right. This challenges our concepts of existence, meaning, and identity.
