Where knowledge must end

I came to the realization today that every generation adds about 30 years of history to be learned in class. Each time something new must be learned, time is taken from older subjects and redistributed to newer ones.

Eventually, I assume, we will simply have too much to learn. At that point I guess we will see a rise in the number of historians. We will require entire agencies of people simply to keep track of all the stuff we have done.
