Elon Musk and his wife, the Canadian musician Grimes, recently announced the birth of the son – and named him X Æ A-12. What does the name mean? No one really knows but theories range from it being a Biblical reference to an Archangel to a tip of the hat to a CIA spy-plane. Honestly, it would have been more shocking and rebellious if they named him Chris. This couple is a constant hoot!
