When Vint Cerf came to give a talk on the K-State campus in October, 2006, I attended and asked a question about ubiquitous computing as is often heralded by visionary futurists such as Vint himself and Ray Kurzweil. He gave very good answers to the question and follow-up questions that I asked him at a later discussion with the CIS faculty.
One thing I've not really paid enough attention to is the logistic and economic challenge of making the Internet sustainable. Some founders of the Internet share a specific vision. One of Vint's pet topics is, of course, net neutrality. Now, I'm all for it, but I'd like to know: how feasible is net neutrality from where you sit?
