I know Korea is a fast-changing place, but while I was there I was taught and often observed that the value of "ppalli ppalli" (hurry hurry) was often applied to mean that a job was better done quickly than right, with predictably shoddy results. Obviously I have no insight into what happened here, but I can easily imagine a group of very hurried engineers feeling the pressure to just be done with their G-Drive tasks and move on to other suddenly urgent things. It's easy to put off preparation for something you don't feel will ever come.

I'm going to check all the smoke detectors in my house tomorrow :D
