    and forget about running 4nm chips in space. shit has to be radiation hardened, which means bigger process nodes and higher energy cost, and lower speed

      Another thing they probably didn’t think of. Nobody’s run chips in space before.

        they did think of it. lots of people have. I just mentioned what was required. Rad hardened processors are usually 10 to 20 times slower than what we have on the surface

          So don’t use rad-hardened processors, put them in a radiation vault instead. Those become more mass-efficient the more hardware you’re putting inside them.

          Really, I assure you the people proposing these things have put more thought and expertise into it than a bunch of random Fediverse commentators.
