Aside from the obvious cooling issues people have already mentioned, isn't cosmic radiation also very unkind to modern ultra dense silicon? AIUI they tend to use really old silicon processes in space stuff for that reason, and even then they have to build in redundant compute to mitigate logic errors that probably wouldn't happen on Earth.

To be fair that's mostly part "if it works don't change it" and part "that's how we've always done it". SpX uses newer hardware w/ traditional OSs (linux) w/ lots of redundancy.
