On Thursday, TIME magazine was shocked once again to discover that humans who were born around the same time are suddenly becoming adults around the same time. In the millennial-centric cover story of the May 20th edition, titled “The ME ME ME Generation” (alternate title: Some Things About Millennials Are Great and Some Things About Them Are Bad But Pretty Much Nothing About Them Is Interesting When Committed to Ink In the Fashion of this Article I Now Realize), author Joel Stein observes that the past few decades' beautiful crop of young people may be “the last large birth grouping that will be easy to generalize about." Of course, this statement disproves his point even as he makes it. (Stay tuned for Post-Millennials: The Un-Generalizeable Generation.)
