Thats not a naive question at all. You’re totally right. The term to learn about this is “rad-hardened computing”. It’s a solved problem, but the solution involves a buttload of redundancy and extra silicon with huge performance reductions compared to non-hardened tech.
It’s less of an issue if you’re in the shadow of the sun but still quite a big issue.
Back in the day every screw on thinkpads had a series of little symbols on them to tell you which ones you needed to undo in order to get to the ram, storage, keyboard, and fans. Without needing a repair manual. I hope they brought that back!
