In the interview, Dick roams over so many of his personal theories about what these “unexpected things” signify that it’s difficult to keep track. However, at that same conference, he delivered a talk titled “If You Find This World Bad, You Should See Some of the Others” (in edited form above), that settles on one particular theory—that the universe is a highly-advanced computer simulation. (The talk has circulated on the internet as “Did Philip K. Dick disclose the real Matrix in 1977?”).
Finally, Dick makes his Matrix point, and makes it very clearly: “we are living in a computer-programmed reality, and the only clue we have to it is when some variable is changed, and some alteration in our reality occurs.” These alterations feel just like déjà vu, says Dick, a sensation that proves that “a variable has been changed” (by whom—note the passive voice—he does not say) and “an alternative world branched off.”
Dick, who had the capacity for a very oblique kind of humor, assures his audience several times that he is deadly serious. (The looks on many of their faces betray incredulity at the very least.) And yet, maybe Dick’s crazy hypothesis has been validated after all, and not simpy by the success of the PKD-esque The Matrix and ubiquity of Matrix analogies. For several years now, theoretical physicists and philosophers have entertained the theory that we do in fact live in a computer-generated simulation and, what’s more, that “we may even be able to detect it.”
