If you're too dumb to understand a fundamental concept like file extensions, which has been around for decades, and remains at the core of desktop computing, you should not be allowed near computers, and you definitely have no say in what computers are, should do, or should work like.
This is an elitist view and there is nothing wrong with that. Don't dumb down desktop computers for those of us who like and understand them as they are. Everyone else can use an iPad.
