What Elon Musk's 'sentient sun' claim reveals about the SpaceX–xAI merger

The article discusses Elon Musk’s recent announcement of the merger between SpaceX and his artificial intelligence startup, xAI, highlighting a shift in SpaceX’s strategic focus from Mars colonization to lunar bases and orbital data centers. Musk envisions this merger as the creation of a "vertically-integrated innovation engine" combining AI, rockets, space-based internet, and real-time information platforms. Central to this vision is the ambitious and metaphorical concept of building a "sentient sun"—a vast, solar-powered AI system in space designed to harness the Sun’s energy to power intelligence at a stellar scale, effectively creating a distributed, space-based "brain" through a constellation of AI data centers and compute satellites. This vision ties into Musk’s recent plans to deploy data centers in Earth’s orbit, which would continuously harvest sunlight and benefit from the cold space environment to reduce cooling costs. Musk frames this initiative within the context of the Kardashev scale, aiming for humanity to progress toward a Type II civilization
