I don't think the issue is that it's new or different. I think the problem is the amount. It feels like pop culture is a firehose now. It definitely feels like the democratization of culture that happened with the rise of the internet has kind of saturated our ability to process things.
I'm approaching 40 and I was online before middle school. This might be the first generation to be wholly raised on the internet (as in the vast majority of children), but it certainly isn't the actual first.
