Silly anecdote time.

I dunno from quantum, but cosmic rays actually *do* cause bit flips
fairly regularily in real life:

Sun Support, for a long time, had just the wrong form factor of
cache RAM on its CPUs for this sort of thing; very dense, very
physically large (inches on a side). Support actually told me that
they had a cosmic ray database; a certain kind of crash/reboot was
almost always caused by cosmic rays, but people couldn't just go
back to their boss and say "Enh, cosmic rays", so they had a
database; the first time it happened, they'd enter the CPU in, and
if it happened again, they'd replace it.


They say:  "The first AIs will be built by the military as weapons."
And I'm  thinking:  "Does it even occur to you to try for something
other  than  the default  outcome?"  See ***
