It's almost as if we default to tending towards imitation and recycling, and only each time a totally new technology changes what is possible do we really try new things -- but the well of newness is rapidly exhausted and so those artisans who are fortunate to be able to be the first to work with a new medium get to be the ones that create its classics.
The question is why? Does a medium combined with a culture totally determine the kind of work that can be made? Or is the influence of the original classics impossible to escape? In other words, is this situation path dependent?
