Only on the "CBS This Morning" podcast, former Cisco CEO and chairman John Chambers explains why forty-percent of existing companies won't be in business in ten years. Talking with CBS News' Don Dahler, Chambers discusses why the U.S. needs to become a start-up nation. A native West Virginian, he provides examples of companies, cities and states that failed to evolve and got left behind. Chambers says "it's better to disrupt or you'll be disrupted." He lays out other insights from his decades of experience in his new book, "Connecting the Dots: Lesson for Leadership in a Startup World."
