I'm sure we've all seen this one. Its usually pinned or shared on facebook, sometimes with an image of young teens bent over their phones, not talking with each other unless it's through text messages. People who pin it will often comment things like "SO TRUE!"
The problem is of course, there is no record of him saying this. Einstein has to be one of the most misquoted historian figures of all times (along with such people as Plato). The quote unfortunately can not be traced back to him, and is not found in The Ultimate Quotable Einstein by Alice Calaprice, who is a renowned Einstein expert.
A bit of research also pulled up this collection of tweets from Waldo Jaquith where he was able to track down the original source of the quote, and it appears to have originated from a downloadable (and questionable) app for your phone. The app in no way sites it sources for the quote, so I'd be pretty skeptical about ANY quotes from this app.
