If you've been pinned under a particularly massive boulder for the past month and haven't heard about Google's latest reveals at its annual I/O conference, you missed out on the biggest gamechangers in tech. But, while much of the focus has been turned to Android M and Google Glass and other software releases, there hasn't been nearly as much press on Project Ara, and that's just ridiculous. Here's what you should know about Google's underrated project and why it's set to change the future.
