The Joke
A person is speaking (possibly at a podium or in an interview) about the simulation hypothesis — the idea that the universe is probably a computer program. They riff on this by pointing out that there was a brief window when you could make a fortune by designing software that nobody likes, and they used that opportunity to found the world's most powerful rocket company, almost ran out of money, then got a billion-dollar contract. They then describe plans to build a house on Mars, smoke crack, and do other outlandish things. The caption below reads: "On reflection, it turns out only Elon Musk lives in a simulation."
The joke is that when you lay out Elon Musk's actual biography and stated ambitions in sequence, it sounds so improbable that the only reasonable explanation is that he specifically — and nobody else — is a character in a computer simulation. His life trajectory is so absurdly unlikely that it breaks the normal rules of probability that apply to everyone else.
The Humor
The humor works by taking the simulation hypothesis (usually discussed as a universal philosophical proposition about all of reality) and narrowing it down to just one person. The comic doesn't argue that we all live in a simulation — just that Musk's particular life story is so statistically improbable that it can only be explained by someone running a very weird simulation for one specific character. The rapid-fire listing of his real accomplishments and eccentricities, when presented all at once, does genuinely sound like the plot of an absurd video game rather than a real life.
References
The simulation hypothesis, popularized by philosopher Nick Bostrom in his 2003 paper, proposes that advanced civilizations would likely run detailed simulations of their ancestors, making it statistically probable that we ourselves are in such a simulation. Elon Musk has publicly endorsed this idea on multiple occasions. The comic references his real ventures including PayPal (software nobody likes), SpaceX (rocket company that nearly went bankrupt before securing NASA contracts), and his stated goal of colonizing Mars.
