All about X
Elon Musk and musician Grimes welcomed X Æ A-Xii in May 2020. Musk initially announced the birth on Twitter, later revealing the unique name. Grimes explained that “X” represents “the unknown variable,” “Æ” stands for “AI” or “love” in various languages, and “A-12” signifies the precursor to the SR-17 aircraft—their favourite aircraft known for speed and efficiency. The “A” also symbolises “Archangel,” referencing a song by Burial.
