    Does anyone understand the math behind this bit?

    > In the right orbit, a solar panel can be up to 8 times more productive than on earth....

      Because the panel is positioned such that it's is always exposed to the sun.

      1: There is no night or day.

      2: There are no seasons.

      3: There is no weather.

      Basically, the primary motivating factor of putting AI in space is abundant solar energy. Otherwise, AI in space makes little to no economic sense.

        To build on the economic/practical issues.

        The useful life of cutting edge AI server hardware will require constant rotation of equipment to potentially remain competitive with more accessible solutions.

        Heat management ( <a href="https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=-w6G7VEwNq0" rel="nofollow">https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=-w6G7VEwNq0 )

        Hardening of equipment for the environment. ECC isn&#x27;t going to be enough. I would have to defer to experts about the best way to manage it, but it either means custom hardware, weight, or both.

        Repairs are impossible. Hopefully a sat can degrade gracefully, but routine repairs on earth become significant outages&#x2F;decreases in economic value of a sat over time.

        Rocket launches have gotten much better, but are not perfect. Insurance is a thing. However, cost of equipment in a failed launch may be eye watering, rivaling a governmental military launch.
