It appears some of you don't seem to understand so let me lay it all out for you:
- A Machine can do everything, and is used to create things for the user. There is a certain degree of understanding required in order to operate a Machine effectively. A Machine is complicated, but not incomprehensibly so, whose mechanics can be intuited easily given enough time.
- A Device can do lots of things, but not everything, and is used to do work for the user. There is not a certain degree of understanding required in order to operate a Device. A Device is vastly complicated, whose mechanics may be intuited, but only fully understood by select intellectuals.
- A Gadget may only do one specific thing, and is used to assist or help the user. There is little to no brainpower required in order to operate a Gadget. A Gadget is incomprehensible, hopelessly complex, whose mechanics remain a mystery to even the highest powers of our mere existence, like a God.
