$1200/lb is the lowest cost to put anything in orbit. A GB200/300 NVL72 rack weighs 3000 pounds. It will cost $3.6M to put 72 GPUs in orbit. It will cost $5B to put 100K GPUs in orbit. That does not include any supporting infrastructure.

This is not hard math.

@sfiruch All you need are big radiators. Assuming power is free, you can just pump a lot of fluid and run a terrible PUE.
