It's actually more dumb if you can manage all of the things to make this farce successful, because high-temperature chips that don't require cooling would work even better on Earth than in space because the temperature resistance could be combined with ambient cooling, and there are far more valuable (and longer-lasting) things that could be launched with greater launch mass efficiency.

Also...hardened electronics have been a thing for decades. It's not big because shielding is cheaper and far more effective. The only practical use is military, and there are already DoD suppliers who are generations ahead of SpaceX on the hardened chip front.
