While Elon Musk is mostly known for making cool cars, awesome rockets, and dank memes, he has a few less-known side hobbies that may surprise you.

One of them is implanting computer chips into monkeys' brains.

Elon said one of his companies, Neuralink, now has "a monkey with a wireless implant in their skull with tiny wires."

The brain-interface company is in the business of making high-tech chips to help disabled individuals with brain and spinal injuries. Similar technology is already being used to help paralyzed patients walk again.

The coin-sized implant has over 3,000 electrodes that can connect with 1,000 neurons. The wires are smaller than a strand of hair.

Elon's greatest ambition with the project, however, seems to be to get the monkeys to play wireless video games with each other in their heads. Because why not?

"One of the things we're trying to figure out is whether we can have the monkeys playing mind pong with each other. That would be pretty cool."

"You can't see where the implant is and he's a happy monkey," Elon said, assuring people that the animals are being treated well in "the nicest monkey facility" on earth.

I mean, that's great that the monkeys are happy, but have you ever watched a sci-fi movie in your life, Elon? It's not the facility I'm worried about.

The first line of the plot writes itself: "Eccentric billionaire creates cybernetically enhanced primates that communicate telepathically with each other."

We all know what happens next in that movie.
