Include spares.

I hope they're reading this thread and taking notes, they probably didn't think of that.

    and the infrastructure and robotics to replace them, of course.

    Assuming 200 nvidia H100 failures a day (conservativo, reality is worse) that's an extra ~340kg of weight you'd need to launch per day. Which is an extra 120 tons yearly.

    So, one Starship launch per year. Doesn't sound like a problem.

    at least two, you can't stuff a rocket full of just gpus, you need something to actually dock and deliver the payload in space. So you need to launch at least 2 rockets (in a non-reusable configuration, so you need to pay for the whole rocket and the launch) to ship a bunch of gpus that are, at best, only 10% as fast as usual.

    Okay, two then. It's still cheap.

    in a non-reusable configuration

    Why do you say that? 120 tons is well within Block 4's projected capacity in reusable configuration. 240 tons is almost within it, even.
