>And security would be a snap—if you can’t see the light, you can’t access the data.
That doesn't make any sense at all. People don't intercept data transmission with their eyes. If your computer or device can "see" the light, so can mine.
I think the point is with, say, wifi, it is broadcasted in all directions, where LiFi would be pointed directly at the destination, which makes it much harder to intercept.
