If education matters, and if human intelligence augmentation matters, then we should be researching how to make difficult technical material more easily digestible, for example by enhancing it with an appropriate level of humour.
Millions of dollars are being spent on making machines more intelligent (or is it billions?). Someone should be spending some time, money and effort on making people smarter.
Also, compared to other possible human intelligence augmentation technologies, writing textbooks in a more humorous style is less intrusive than taking "smart pills" or placing electrodes inside your brain.
