For years, there's been a sort of Chicken Little mentality in radio, even going back decades: cassettes will kill radio (people will record their music off the air, and then never tune in again), satellite "radio" will kill radio, web streaming will kill radio. A lot of people in the industry have been running scared, thinking we could be out of business any day now. Even the former head of NPR stated a few years ago that within a decade, all of our towers would go away.
I'm not saying technology doesn't pose challenges for radio, but we still have a lot of strengths. Seth Stevenson at Slate does a pretty good job of outlining them in an article you can read here.
