【Three Female Ghosts】

Tech mogul Elon Musk and Three Female Ghostssinger Grimes have something in common: they blend art history with artificial intelligence to make the nerdiest, most niche jokes.

The new couple arrived at the Met Gala together -- Musk in a white priest-looking tux and Grimes dressed as a goth robot.

According to Page Six, nerdy, niche jokes are the reason the two are a couple. Apparently, Musk wanted to tweet a joke about AI, but Grimes had already made it.

Roko's Basilisk is a thought experiment that questions the risks of AI, hypothesizing a reality where potential robot overlords take over and punish humans who didn't help bring it into existence. Rococo is a style from the end of the French baroque period, characterized by ornate decorations, dense ornaments, and theatrical asymmetry.

Musk wanted to combine the two into "Rococo Basilisk," which Page Six muses might be a play on how ridiculous and complex both concepts are.

It's a joke that about two people in the entire world would probably get.

Those two people just happen to Musk and Grimes. Grimes made the pun three years ago, creating a character called Rococo Basilisk for her song "Flesh Without Blood."

She told Fuse that the character "is doomed to be eternally tortured by an artificial intelligence, but she's also kind of like Marie Antoinette."

An "insider" told Page Six that while Musk was researching the concept, he saw that Grimes had already made the pun and reached out to her. The anonymous source said it was the "first time in three years that anyone understood the joke."

Since then, they've been flirting on Twitter in the least subtle way.

Then on Monday, a few hours before Page Six published its story on Musk and Grime's relationship, Musk cryptically tweeted "Rococo Basilisk."

Some Twitter users had some strong feelings about the new couple's relationship status.

But with their Met Gala debut, at least Elon Musk and Grimes can be super nerdy together.
