This is a good question, but I don't think this will necessarily happen for two reasons. 1) With more scientific advances we will hopefully be able to live longer 2) The better we understand a field, the more we can compress and simplify it and have an easier time teaching it. At least this appears to be the case in mathematics, where I can only imagine many years ago something like trigonometry was not well understood and the greatest mathematicians of the time did research to further our understanding of it, but now it's something we're expected to learn in high school. I can only imagine this will happen as well to the current topics of research as well.
