People can only do single-threaded concurrency, we have absolutely no way at doing true parallelism on a cognitive level+
I really don’t see the parallel you are trying to draw, computers do what they are instructed to do with very very very little chance of a hardware failure. Not wanted operations can happen, but they ultimately boil down to human error.
+ We are otherwise a heavily distributed system which has many autonomous systems interoperating at the same time
The parallel they are drawing is for multitasking on single-core computers, for which performance is impacted somewhat similarly to humans.
Of course, the same parallel cannot be drawn with multitasking on multiple cores; though other issues of communication between cores can (and have, extensively) be compared with parallelism between multiple humans.
How many cosmic ray bitflips happen? Even without ECC ram I’m fairly sure I have never seen any affect me, so there is that (even data hoarders with terabytes of data stored with e.g. ZFS seldom report problems due to that - when they start to see checksum errors it likely means a soon to fail harddrive instead)
Also, if I’m not mistaken, in airplanes which are much more likely to get hit by cosmic rays at high altitude, they often use redundant CPUs that work in lockstep with each other. So.. in the end it is human error I guess? Handling unexpected cases should be done well as well.
