In this episode, Riz interviews well known NYU philosophy professor, David Chalmers, who has a new book out called "Reality+: Virtual Worlds and the Problems of Philosophy '', which touches on most of the topics that Riz has been exploring on this podcast. Chalmers also wrote a famous essay, "The Matrix and Metaphysics" in 2003 and was one of the first philosophers to take the issue of virtual reality seriously. If you are interested in the metaverse, virtual reality, simulation theory, AI virtual humans, Digital afterlives and uploading, not to mention how all of these intersect with philosophy, you won't want to miss this conversation!
