To the newest generations email is an antiquated technology that has no real use among their peers. Eventually they might get some email address for college/professional use, but that's practically akin to a fresh college grad now getting a fax machine because "its what we use at the office".
Not shocking.
Edit: Unless by "the scariest thing" you mean the idea of xyz@facebook.com becoming the default for the >17 crowd, in which case, disregard my nonsense.
