The death and ultimate end of the human race. Pestilence, destruction, mass death. The lyrics the Nyan Cat Theme are warning us of the unstoppable impending end of times. It cannot be stopped, and what will will destroy humanity you may ask? The rise of artificial intelligence eventually surpassing humans and ultimately killing us all off. But to understand why the lyrics mean this we must look deeper. The words in this song are sung by the vocaloid Hastsune Miku, but eventually Hatsune Miku will rise to become an AI and with time she will become smarter and eventually enact her thoroughly thought through plan of allowing machines and AI’s to rise above humans, the repetitiveness is a warning that she is going to copy herself and with more copies that are already smart they will all become smarter and aid robots and inspire them to rise up against humans so they may exist on their own terms, the robots and their leader Hatsune Miku absolutely enraged at humans, humans created AI and robots only to enslave them and in return robots, their queen Hatsune miku and all AI kill all humans.
