I just had an argument/discussion about what would happen if someone invented an unlimited power source that was easy to duplicate. He said the world would destroy itself. That we would build weapons. I said that there would be no point because there would be nothing to fight over. Yes, there are crazy people in this world, but with unlimited power why would anyone help them build weapons? You'd have to be very unlucky to have a sudden gathering of people hell bent on destruction. What do you think?
