Noted: François Ortalo-Magné, dean of the University of Wisconsin?s business school, says fissures have already appeared. Recently, a rival school offered one of his faculty members not just a job, but also shares in an online learning start-up created especially for him. ?We?re talking about millions of dollars,? Mr. Ortalo-Magné said. ?My best teachers are going to find platforms so they can teach to the world for free. The market is finding a way to unbundle us. My job is to hold this platform together.?
