Dr. John C. Lilly, noted Dolphin scientist and pioneer researcher into the nature of consciousness (invented the isolation tank), and whose life the movie "Altered States" was LOOSELY based on, mentioned in an interview for Omni Jan 1983:

"Have you seen the movie Tron? You must, because Tron is us. In it, the computer grabs the character played by Jeff Bridges and takes him inside, making him a program In the computer. The Master Control Program revolts, takes over the computer, and defies the users. So the users send in Tron, which is a program to destroy the Master Control Program that is preaching disbelief in the users.

Tron shows you things that are very, very spiritual. You can think of yourself as a biocomputer or an intelligent terminal, run by a cosmic computer in the Earth Coincidence Control Office. The biocomputer contains certain wired-in survival programs dealing with eating, reproduction, and so on, which lower animals also possess. But when the biocomputer reaches a certain threshold of complexity, there are higher-level programs in the association cortex that permit such things as making models, learning to learn, choice, and so forth. We have short-term choices, but God help you if you go against the Master Control Program. A terminal cannot understand itself, because it lacks sufficient space, but a replica of itself is in the cosmic computer, which can understand it. At the highest level, your true self (the "user" in Tron) is a cosmic game player, with access to an infinite computer -- the ECCO computer. That is metaprogramming, self-metaprogramming..."
