It's no secret that Elon thinks we're all living in a simulation. He's stated before that he believes there's a one in one billion chance that we weren't all living in a simulation. He recently posted some some cryptic tweets hinting at our existence and the reality we might or might not be living in. Also, a recent report says that Mars might not have attributes that support terraforming with "current" technology. Terraforming is the only way the planet will be able to support human life, so maybe we'll have to wait for Elon to invent something that will solve this problem? He might not have the time to do that if he keeps hand delivering Teslas to customers. A recent Tesla buyer posted photos online showing his Model 3 arriving with Elon personally accompanying the delivery.
