Set aside for a moment this specific issue (which all in all did not create particular damages), I wonder what is the actual authorization/implementation procedure in a firm like Google to actually push these "potentially destructive" updates (or tests or whatever you call them). I mean, I imagine that there is a control room where people receive an order by the president, together with a launch code, then an officer in command retrieves the other half of the launch code from a safe he opens with a key he keeps at all times on a chain around his neck, and then two other officers, each one with at least 5 years of service and the grade of captain enter the code and press simultaneously two buttons on two consoles rather far apart. But I fear that the procedure is much simpler and - theoretically - at the reach of a disgruntled or "gone mad" employee, hired only a couple months before...
