Tom Leighton as interviewed by the WSJ:

The problem is that you’re going to be increasing the expectations of end users, and the data centers can’t keep up. People think about the “last mile” of broadband (the last link that extends broadband to users). But if there’s not an adequate server at the other end, you’re not getting those 100 megabits per second. The bottleneck is upstream.
