Grimes fires back after Musk corrects her explanation of son's name

The couple, who announced the birth of their baby boy on Tuesday, chose an unusual moniker for their son: X Æ A-12 Musk.  Grimes explained the name in a tweet, saying that the X stood for “the unknown variable,” and that Æ was a reference to both love and artificial intelligence. Great in battle, but non-violent.”  Unfortunately, she made a slight error in her tweet, which the SpaceX CEO was all too quick to point out.  •X, the unknown variable ⚔️ •Æ, my elven spelling of Ai (love &/or Artificial intelligence) •A-12 = precursor to SR-17 (our favorite aircraft). He has six sons with his ex-wife author Justine Wilson, including a baby named Nevada Alexander, who died in 2002 at only 10 weeks old.
