"We envision a system where all Defense Department computers worldwide are connected with reliable networks based on packet switching." I'm sure language like that was in the original proposal for ARPAnet circa 1968, and I'm sure most professionals looked at that and were "very, very skeptical". DARPA has that "advanced research" in its name. If most professionals aren't "very, very skeptical" about the ultimate commercial success of their projects, I'd say they are doing it wrong.
