Change - generational pull, not technology push

Just a quick comment on Seth Godin's post today "Welcome to the frustration decade (and the decade of change)": http://bit.ly/DecadeOfChange
I wholeheartedly agree with Seth's assertion that the maturation of the first internet generation has incredible significance as a dominant force in shaping the coming decade. I like to think that this will accelerate the pace of innovation and adoption of new technologies in HCI. For example, why has it taken so long for the touch-screen to make it to consumer products (not just in ATMs and kiosks) - to me that's the unspoken achievement behind the wild success of the iPhone: it brought touch-based interfaces mainstream. How will that, along with other HCI innovations, change not only our interactions with systems but also the design of the systems themselves? (And in asking this, I mean a cybernetic view of a system in that includes the functions and processes both technical and social - I touch on this ever so slightly in my earlier post, here.) Granted this success is as much about the technology that made the UI so popular. The tech savviness of the internet generation together with the advances of technology promises to be a powerful force of change, innovation and growth.
