Every generation does it, just look at collegehumor.com.
For most of human history, culture has changed little from generation to generation, meaning it was hard to get nostalgic about butter churns and laudanum if they were still prevalent. Throughout the 21st century, generational differences grew at an exponential rate, and everyone eventually found themselves cut off from much of the culture they grew up on. That's not a comfortable idea for most humans. If the culture keeps moving this fast, I think we're all gonna feel like regressing to a simpler time.
On a tangent, it's not unreasonable to suggest that generational differences will keep growing wider, I don't think the divides will be along the same lines. There was a pretty significant ideological revolution that happened during the sixties and seventies, and as a result I see more similarities between the views of the teenaged and middle-aged people I know than between the middle-aged and old. New technology should continue to mystify those who didn't grow up within it, but the progressive ideals which made so much headway in the Sixities and Seventies are widely held by today's youth, negating a potential contrast which existed between the boomers and their folks.
