Li-Fi Goes Past Wi-Fi

Many of us sit and wonder, "What's next?" We don't try be a tech news source but this is so cool, and, we're guessing, a game-changer.  Li-Fi uses any  LED light in a room into a communications device, much like Wi-Fi, at line-of-sight frequencies.  I expect this to be installed in every wireless device within in a few years.  We're not good at predictions, and we're not investing in this thing...but what a great idea.
