> 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.

This is so obviously false. For one thing, in what fantasy world would the ongoing operational and maintenance needs be 0?

They'll just be decommissioned and burn up in space. nVidia will make space-grade GPUs on a 2-3 year cycle.

>>moomoo+l7
They don't need to be space grade, consumer hardware will do just fine.

For AI a random bit flip doesn't matter much.

>>pantal+G7
Random bit flips might even improve output.

>>ohyout+Q9
Single upset events in a modern GPU are not bitflips. They destroy the surrounding circuitry and usually disable the whole unit.

>>adastr+Pd
If that happens you disable that CUDA core. If you GPU is too damaged, you deorbit the satellite.

>>pantal+rg
Yeas, and this will happen within weeks of launch with the orbits under consideration.
