They'll be here soon enough. Thanks to effective new advanced technology, they'll probably be fast zombies, of course. The really scary kind.

This happens a lot in software development. A newbie notices that by making tiny changes in a program they in all likelihood will never understand, they can produce dramatic changes in the interface or behaviors of the program when it runs.

Eventually the program is corrupted so badly it begins to display critical faults and showstopping errors.
