The speaker proposes a "new conspiracy theory" centered on a potential merger between Tesla and SpaceX. The core idea is that Elon Musk might envision a scenario where Tesla's future "cash flow off of robo-taxis" could be used to accelerate SpaceX's ambitious projects. Specifically, this cash would be invested in speeding up Starlink development and, "particularly," in establishing "AI orbital data centers in space." The speaker concludes by framing this merger as the "fastest way for SpaceX to hit a trillion dollars in revenue."
