This is really the the take home point of this article for me:

People don’t worry about the idea of a Generation Gap anymore. That notion has been replaced by a Technology Gap. The possibility of parents and children sharing the same cultural interests has increased dramatically over the past 25 years; today, the central bifurcation is how that communal culture is accessed and interpreted and experienced.

I should suspect the "technology gap" (if this is what we are going to call it) to completely replace the generation gap in the not-to-distant future. And this should also restructure all social lives and relationships as age, biological relatedness, as well as traditional social structure morph into something completely different in the 21st century (this of course working under a Singularity paradigm).
