When this comes to pass, I am going to call you for instructions on how to hack into my shower.
Hacking takes on many forms. For example, once upon a time, hackers used to be called "gear heads", among many other different monikers. Anyone who can take anything, and use it for other than its original purpose, or expand beyond its original purpose, is a hacker.
They've been around for thousands of years. In a sense, this country was built by hackers.
