Sign of the Times


There will be a time when we will rely on our cell phones to schedule our day.  On some scale I think the big advantage of handheld technology is organization.

May the holidays bring your peace and joy.

Sign of the Times

Soon a reader will replace textbooks.  One advantage will be that a student will have the text her whole life.  The average student carries 50 pounds of textbooks around in their backpack.  Students will be grateful and perhaps Amazon will be too since they will be able to control who has access to their content.

Human Capital Technology and Production

Using an iosquant that shows all of the production possibilities for making 10 jet skis in a day, this graph shows that increasing the level of knowledge from 2 to 4 reduces both the amount of kapital and labor needed.  Technology makes us smarter.  Let's assume that a teacher, Mr. Applebee, finds that his job becomes less labor intensive when he can digitize his lectures, worksheet, and use videos in his class.  So, Mr. Applebee substitutes kapital for labor.  Suddenly, his job becomes a lot easier.  Now as technology improves, so does his instruction as he can now extend his teaching to students around the world.  Perhaps sharing buttons allows him to post simultaneous to Facebook, Digg, and Delicious in a second.  My question is now that the content has been digitized and the marginal cost of sharing is zero, what good is Mr. Applebee?  I think that administrators will recognize this and substitute technology for Mr. Applebee.
