The person who's going to come up with new idea's isnt spending their time memorizing old ones. They learn to index where to retrieve knowledge when necessary in order to allow them to cover a wider breadth of knowledge. And this will allow themand to pick the best one for the job at hand as opposed to the tool they are an expert in. Sometimes you need a handyman instead of a master plumber because they are better able to see the big picture beyond all the shit.
