You mean communication, the transfer of ideas. Already hard between humans, machine language and operation is completely foreign.

No, I mean language. Even if you are alone with yourself in a solo project, you need language to structure your ideas. Communication is when you need to transfer these structures in place (you and a team) and/or in time (you and yourself in different points in time). But it's first and foremost a problem of language, of giving structure to reality.
