I don't think anybody who trivializes Facebook is speaking to the problems they have to tackle at the scale they're at. I think the real cynicism comes from the real added value coming from Facebook at the cost to society it brings (i.e. lost time, ad sales, impact on human interaction, etc.).
Impact on human interaction is a concern in the age of social media. We will always find a way to lose time. I'm not sure if any generation is/was immune to that.
