Never is a long time (Disruptive Technology and the Web) In 1997 Clayton Christensen published a book "The Innovator's Dilemma" which made us look at the world in a completely new way and introduced the term "Disruptive Technology". All around us we can see disruptive technologies at work, displacing existing technologies; the Web itself is clearly a disruptive technology for several existing things. But how about within the Web? Are there emerging technologies that demonstrate some of the properties of disruption, where we could expect at some time they will replace existing technologies? This talk will discuss how to identify potentially disruptive technologies, and which web technologies may qualify.
