I found this article about secret kill switches in computer chips pretty interesting. The concept is that defense suppliers are building backdoor on-off switches in the chips that run advanced weaponry, and anyone who has the secret code can shut those weapons down. I mention it here because I used the idea as a plot launcher for my early superhero deconstruction from Epic Comics, THE ONE back in 1985.

The comics are long out of print, but you can buy a signed copy of the King Hell trade paperback edition of THE ONE from my on-line store.
