Patching works differently with social systems than with technological systems. With the latter, the patch makes the latest hack no longer possible. This is obviously true for software, but extends to other technological systems as well. ATM manufacturers can patch their machines so that a particular jackpotting hack simply doesn’t work anymore. A casino can deal blackjack from a six-deck shoe that continuously shuffles the cards. Financial exchanges can restrict trading to ten-second intervals, making hacks like high-frequency trading impossible.
