since, if it were found to be true, such knowing may end the simulation. Greene's suggestion is similar to Douglas Adams' humorous idea presented in his 1979 novel The Hitchhiker's Guide to the Galaxy: that if anyone in the Universe should actually work out 'The Meaning of Life, the Universe and Everything', it would instantly disappear and be immediately replaced with something "even more complex and inexplicable". Metaverse If people transition most of their lives to virtual metaverse worlds, there is the potential for those virtual worlds to present those people with false truths, thereby diverging people’s perception of reality from true reality. Whereas fully simulated realities face significant technical challenges to create, divergent virtual realities are easier to manufacture if societies transition to fully operating in virtual metaverse worlds. This near-future variant of the Simulation Hypothesis was explored by professor and science fiction author Tadayoshi Kohno in “The David and the Fig Leaf.” In fiction, architecture, and celebrity takes Simulated reality in fiction has been looked at by many authors, game designers and film directors, most notably explored in the 1999 film The Matrix and portrayed in the 2018 film Ready Player One. In 2012, a Der Spiegel editorial article, referring to the computer-generated images of the Seven Houses for No One series, prompted debates about simulated reality in architecture: "The young Italian architect Antonino Cardillo took advantage of the fact that fiction and reality can hardly be distinguished. Der Spiegel learned that Cardillo had sent pictures of supposedly built buildings to architecture magazines and made it appear that the houses had actually been built. But these only existed virtually."⁠ Elon Musk, the CEO of Tesla and SpaceX, has had much to say about the concept that our reality is a simulation including: "The odds that we are in base reality is one in billions" which he said at a conference in 2016. Musk has also speculated that the odds of us living in a simulated reality or computer made by others is about a 99.9% chance at various other press conferences and events and on the Joe Rogan Podcast.
