The Open Source Paradigm Shift

This article is based on a talk that I first gave at Warburg-Pincus’ annual technology conference in May of 2003. Since then, I have delivered versions of the talk more than twenty times, at locations ranging from the O’Reilly Open Source Convention, the UK Unix User’s Group, Microsoft Research in the UK, IBM Hursley, British Telecom, Red Hat’s internal “all-hands” meeting, and BEA’s eWorld conference. I finally wrote it down as an article for an upcoming book on open source,” Perspectives on Free and Open Source Software,” edited by J. Feller, B. Fitzgerald, S. Hissam, and K. R. Lakhani and to be published by MIT Press in 2005.
