How silly would it sound to say, because few people can play the musical instruments required to record a song and then edit and produce it, that sharing sheet music, recorded loops, etc is a waste of time and has not really improved music?
Both that example and free software are remix cultures, and the same logic is used to shit on free software apparently. Piracy for example is not a remix culture; you don't get anything other than the end result to try to mess with.
And as I said in A Parastatal Problem, even if only a few people can read published source code, they are now in a better position to write software that you may already use. If you think that's insignificant, then a. fuck you and b. go throw your computer on the street and make sure you never use any online service, telephone, or any computerised system ever again, because they're insignificant apparently.
