When people started suggesting the names of strange planets and sounds for Elon Musk's seventh child, they took it seriously. And maybe Musk himself took it so seriously. The latter, when asked by a follower on Twitter about the baby's name, wrote X Æ A-12.
Clarification: At first, people thought they were joking, but when someone took the time to try to decipher the code, the name made sense. All the more so since Musk liked the post. The follower suggests that it is related to the Scandinavian alphabet and pronounced / Ash /, while A-12 refers to a CIA aircraft, code for Archangel. Ash Archangel? X still remains unclear. Change X? X-axis? Whatever it is? Here we also surrender.
