I suspect there are many more sources of risk that result in only being able to approach complete safety than cosmic rays, but this seems a reasonable argument for at least establishing that the limit exists so even if we disagree over whether something more easily controlled by AI design is a source of risk we don’t get confused and think that if we eliminate all risk from the design that we suddenly get perfect safety.
