The problem with having an idea is getting that idea out of your brain and into the brains of other people. Even if you achieve this thought transfer, how do you know they have the same idea and not an altered one? Brain sharing is not an option, so we use our bodies to convey the idea, voice(including tone), hand/arm movements and facial expressions or a pencil and paper or a keyboard. The skill of the person with their chosen tool (such as me with this keyboard) determines whether the actual message received was the one sent. We call people proficient with a chosen communication media, Artists. In the end, the more tools or steps required to convey the original idea (hence the more translations) the more likely the original idea will be altered in the audiences minds. Just like this comment – I saw it differently in my head.
