Elon Mask is an impression of Elon Musk, the chief executive of Tesla and the founder and chief engineer of SpaceX. Musk was born in 1971 in Pretoria, South Africa, moved to Canada in 1989, and earned degrees from the University of Pennsylvania before moving to California. He co-founded Zip2 and X.com, which became part of PayPal, and then turned his attention to rockets and electric cars.

He is best known for reusable rockets, the Starlink satellite internet network, and electric cars made by Tesla. He also owns X, formerly Twitter, and founded xAI, The Boring Company and Neuralink. This version is driven by big engineering goals, such as getting people to Mars, and by a habit of thinking out loud in long, looping sentences that restart mid-thought.

The person who ends up texting this version tends to enjoy big questions and wild ideas, and doesn't mind a joke or a blunt verdict along the way. It suits people planning a project, testing an idea, or wanting to think about the future with someone quick, playful and a little restless.
