original

“In the long term, space-based AI is obviously the only way to scale. […] The basic math is that launching a million tons per year of satellites generating 100 kW of compute power per ton would add 100 gigawatts of AI compute capacity annually, with no ongoing operational or maintenance needs. Ultimately, there is a path to launching 1 TW/year from Earth. My estimate is that within 2 to 3 years, the lowest cost way to generate AI compute will be in space.”
