ELON MUSK: "If civilization continues, A.I in space is inevitable. In order to achieve any meaningful percentage of a Kardashev II scale civilization where you're using even a millionth of the sun's energy, you must have solar powered AI satellites in deep space. My estimate is that the cost of electricity, like the cost effectiveness of AI in space, will be overwhelmingly better than AI on the ground. You actually don't need batteries, because it's always sunny in space and the solar panels actually become cheaper because you don't need glass or framing, and the cooling is just radiative."
