   DATA CENTERS IN SPACE MAKES NO SENSE (2 MINUTE READ) [7]   
      
   Data centers in space face massive challenges such as radiation,   
   cooling, latency, and launch costs. There are other fundamental issues   
   that make them unfeasible: competing in the market would require   
   launching hundreds of thousands, if not millions, of satellites into   
   space, and satellites can't be upgraded at scale. Data centers in   
   space only make sense if they are cost-effective relative to normal   
   data centers. The idea makes less and less sense with every   
   improvement in normal energy production.   
      
   Training and serving frontier AI at scale takes hundreds of thousands of GPUs.   
   xAI's Colossus cluster reportedly has 200,000 GPUs. OpenAI has plans for   
   millions of them. Competing in this market would require launching hundreds of   
   thousands, if not millions, of satellites into space. This would utterly dwarf   
   the roughly 15,000 satellites that are currently orbiting the earth. Satellite   
   deployments at this scale would dramatically increase the risk of Kessler   
   syndrome: a cascading explosion of debris crippling our access to space.
