IT Conversation site (worth bookmarking, BTW) has John Smart's talk about changes, technology an future. The full title is: Simulation, Agents, and Accelerating Change: Personality Capture and the Linguistic User Interface.
The talk is long (65 minutes). What is interesting for me is that he referes to changes, not revolutions. He talks about new technology replacing the old one - using "less matter, less energy, and less space".
I don't agree with all, but it's definitelly worth listening. The abstract presented before you download the file (BTW: registration is optional) doesn't cover all main topics. Better summary can be found in Kaedrin Weblog
