AI leaders are exploring the possibility of building data centers in orbit due to concerns about Earth's limited land and energy resources. Companies like Google, with its Project Suncatcher, and figures such as Elon Musk, Jeff Bezos, Sam Altman, and Jensen Huang, support the idea, with some predicting space data centers within five years. This concept emerges amid massive investments in AI infrastructure and fears of a potential bubble, as earthbound data centers face increasing power and land constraints.
