July 2, and I'm sitting in terminal 2F in Paris, waiting for the Cairo flight to board. It is fitting that this year's Imagine Cup destination builds on last year's competition in the City of Lights, from a sustainable environment to a sustainable world.
I am reminded how often innovation stands on the shoulders of the work that has gone before. Not that the path is always continuous; it is often one of disruption, as Clay Christensen aptly notes. Yet the new presupposes the old even as it breaks new ground in new ways. I will be looking for the disruptive ideas with the appreciation of the eyes of a veteran.
