Note here that this analogy only goes so far. The sciences of medicine and agriculture have come leaps and bounds since the start of the industrial revolution and our outputs and expectations for both with respect to humanity have increased tremendously.
Not so with education. While we have dramatically increased the amount of information, there still seems to be a limit to how much an individual can learn.
César Hidalgo calls this limit the personbyte.
The perennial question for education technology is how might we get around this limit?
The only solution in some areas is new discoveries concatenating and compressing some of the knowledge by abstracting it to simpler spaces, as sometimes happens in physics, but generally this is relatively rare. (or is it? justify...)
