Gavin Baker (@GavinSBaker): "The most important thing in the next 3-4 years is data centers in space.
In every way, data centers in space, from a first principles perspective, are superior to data centers on earth.
In space, you can keep a satellite in the sun 24 hours a day. The sun is 30% more intense, which results in six times more irradiance than on Earth. So you don't need a battery.
The cooling in these data centers is incredibly complicated. Space cooling is free. You just put a radiator on the dark side of the satellite.
The only thing faster than a laser going through a fiber optic cable is a laser going through absolute vacuum.
Link satellites with lasers, and you have a faster and more coherent network than any data center on Earth."
