once upon a time everyone knew how to drive manual transmissions, because thats all there was; just like once upon a time, everyone knew how to write code and use command line interfaces because thats all there was.

Now we have GUIs and automatic transmissions.

Stick shifts can sometimes function as a sort of rudimentary security system: not as many people know how to drive them, less demand/competition, less expensive, and therefore less likely to be stolen.

Might, command lines, eventually take a similar path, that they become less hackable because people are less likely to know how to use them?
