It really pisses me off when people are entirely ignorant of history. Come on, guys; the simulation theory was cliche by the early 1960s. In 1999, there were two hit movies about it, one of which was a direct adaptation of a book from the 1950s that had already had three other popular film adaptations. During the 1960s, PKD alone wrote five or six separate books about it, and in 1977, he gave a pretty well-known lecture that set forth a number of arguments accepted later by Bostrom. By that point, it had already been the plot of two different Doctor Who serials.<p>Stop saying somebody is the first to do something, unless you've actually done the research.
