Energy constraints in the artificial-intelligence race are causing tech companies to think out of this world. The world’s richest men are earnestly talking about traveling to outer space to build gigantic data centers to run artificial-intelligence models among the stars. They argue such missions make the most sense for powering energy-hungry operations. Such talk comes as Jeff Bezos’s Blue Origin and Elon Musk’s SpaceX rocket companies are working to make space travel cheaper and routine. It isn’t clear what’s closer to being real: Moon bases or superintelligent AI?  The argument essentially boils down to the belief that AI’s needs are eventually going to grow so great that we need to move to outer space. There the sun’s power can be more efficiently harvested. To be clear, the current economics of space-based data centers don’t make sense. But they could in the future, perhaps as soon as a decade or so from now. Now Tech Moguls Want to Build Data Centers in Outer Space – WSJ
