I believe that Michael Saylor announce this about 13 year ago (in 1999). If I remember correctly, he had a column in Newsweek or Time talking about it. Then Microstrategy's stock tanked (they had to restate their earnings), and his fortune pretty much vanished overnight.

It's interesting to see how much has happened in the past 13 years, and how technology has made this kind of thing feasible. The proliferation of high-quality online educational companies (Khan Academy, Udacity, Coursera, etc...) has made it possible to get a real education online. It isn't quite equivalent to live education, but the best online education is definitely getting close.
