The words Rococo basilisk are a joke mixing together an art style from 18th century baroque (Rococo) and Roko’s Basilisk – a thought experiment in which AI is capable of torture.
Apparently, when researching his own joke, Musk discovered that Grimes had made the same joke back in 2015 and reached out to her.
A source told Page Six: “Grimes said this was the first time in three years that anyone understood the joke. They were both poking fun at AI.”

Now, just months after their separation was confirmed by Musk, Grimes has released a track that people believe is a dig at Musk.
The song features lyrics that reference being “in love with the greatest gamer” and “he’ll always love the game more than he loves me”.
Pointedly, she also references space travel – something Musk has been heavily involved in through SpaceX.
She sings: “Sail away to the cold expanse of space, even love couldn’t keep you in your place.”
