I guess overall it will take 100 years to go from the russian formalists (eg Jacobson, Propp, Tynjanov) attempts to apply scientific methods to literature, to where engineering is a necessity in creating relevant literature. And at halfway point the early Artificial Intelligence initial optimism. I am not talking here of engineering in terms of word processors and digital print production but to a day where formal models have user interfaces to help us generate content. So to complete the circle from seeking to view literary systems in an evolutive framework separating the literary act from criticism and such, to a view of literature where software is used to create easily interesting to read content, completely adapted to your previous reads.
