It's interesting to think about how much of those changes will be due to new technology enabling new ways of doing things and how much will be due to simply superior knowledge. Consider, for example, what someone going back in time to the early 19th century or earlier would be able to improve just by giving instructions, assuming they'd listen. Pasteurization, sterilization, hand washing, the germ theory of disease, etc, etc. Even things like blood type and how to do transfusions effectively. I suspect that in the future there will be a few "boil water" or "wash your hands" type lessons learned that will affect how we do medicine that aren't dependent on futuristic technology.
