The allegory of the cave is one of the most well-known philosophical examples. The idea is that. If people see only the cave's wall the cave is their entire world. All information that people in the cave get delivered by some other people. That means the goodwill of those people determines what kind of information those people in that cave get. So we can say that Plato's Allegory of the cave is the first case of synthetic reality. What differentiates the people in Plato's cave from the people who are serving in the underground nuclear weapon facilities? The fact is that those people who are serving in those underground facilities get also information that other people want to share with them. In the modern nuclear center, high-tech screens have replaced the shadows on the walls. But the set is the same as that cave about 500 B.C. The screen just transmits information to people who are fully isolated. Allegory of the cave (Wikipedia) Internet is the next-generation Plato
The quantum computer makes the revolution in artificial intelligence. Quantum computers can drive more complicated codes than ever before. And the fast development of that technology makes it hard to predict what kind of solutions will be born in the future.
