I also suspect that Cesar Hidalgo’s text Why Information Grows: The Evolution of Order, from Atoms to Economies may provide a strong clue with some details. To some extent I think we’ve generally reached the Shannon limit for how much information we can pour into a single brain. We now need to rely on distributed and parallel networking among people to proceed forward.
I bookmarked a great post by Jim Luke (@econproph) a few weeks ago on scale and scope. I suspect that tech’s effect on education is heavily (if not permanently) scale-limited, but scope may be a better avenue going forward.
