I can't personally agree with that statement that humans aren't intelligent enough to write music forward and backwards that is comprehensible. With enough knowledge and studying of music, mathematics, reading, writing forward and backwards along with practicing speaking forward and backwards I would be able to write music like that. But it would take years of studying. The people in power have "Think tanks" the individuals in the think tanks are more then likely very intelligent and very skilled. You aren't giving humanity enough credit in my opinion.
