Some man told "Actual technologies do not require believing, if they are real. They just work or they don’t."
BUT wait - NO. Thomas Edison two thousand times try to create working Light Bulb but they simply don't work. He was stubborn and believed that it is possible. After long period of unsuccessful result he succeeded. Real technologies require truly believers.
If mankind would solely consists of people thinking that "Actual technologies just work or they don’t" such mankind is doomed to live in a dark.
