"is actually common sense"

Everything is common sence untill it isn't.

Its common sence that you can't take over control of a car over the internet and kill everyone in it, that acess to a website that shows realtime location of half of US polulation would at least be properly protected, that a car's accelerator pedal doesn't cause random and unpredictable effect thanks to spagghetti code, that when Fujistsu charges a postman for theft, they are not just covering up bug in their tracking and accounting software.
