The Thirteenth Floor (1999)
According to The Thirteenth Floor, fully realistic virtual worlds would exist in the 2020s. While the video game industry is getting closer and closer to simulating reality, there’s currently no information that suggests that there will be fully realistic virtual worlds before the decade ends.
Loosely based on Daniel F. Galouye’s 1964 novel Simulacron-3 and a remake of the 1973 German film World on a Wire, The Thirteenth Floor centers on an heir (Craig Bierko) to a multibillion-dollar computer company who discovers an incredibly rendered simulation of Los Angeles in 1937, in which the simulated beings have no idea they are being simulated. Later in the movie, the hero finds out that the 1999 Los Angeles where he lives is also a simulation and that he’s actually from the year 2024.
