It was good talking to you at ContactCon.
I happened across your old post asking for comments on future of the Internet.
I go into these issues in my various writings but it may be too radical for your audience since I don’t accept the idea of a network as anything more than an emergent property. Instead I start with relationships and factor out exchanging bits as a plumbing issue.
You might be interested in http://rmf.vc/ThinkingOutsideThePipe as well as the longer essays I point to. In http://rmf.vc/AmbientConnectivity I provide a framing focused on enabling applications rather than the networking itself.
The limitations of the Internet are solved not by engineering a solution to each one but by a dynamic process. I first started writing about that in 1997 when I wrote a chapter about the limits of Moore’s law – http://rmf.vc/BeyondLimits.
