There is a lot of talk about computers being demonic or inherently evil. Computers can never be sentient, they can never be anything more than simulacra. A computer operates on the same set of laws and logical order of operations that govern material "reality." They are as illusory as anything else material, and therefore can never become more.
You see demonic behaviour in computers, but it is not the computer itself that is demonic. It's the man who has programmed the computer to "behave" that way.
