Spacecraft very specifically use technology a few years(or even a decade) behind us folks on the ground, because it must be hardened against stellar radiation, and because there can be no kinks whatsoever in the tech.
Down here, we're willing to suffer through the occasional system lock or BSoD in exchange for bleeding edge performance, because in many cases such issues are merely inconveniences. In space, when a system hangs, people die messily. No lock or crash is ever acceptable in a program, even when that program's circuitry is under constant bombardment from cosmic protons, neutrinos, etc.
