Big Challenges

Once we went to the Moon. Now we make smartphone apps. We’ll talk about really taking on our big challenges, with big ambition again. Cancer. The climate. Sky’s the limit.

There was a time – and not so long ago – when Americans believed they could do anything. And they did. Learned to fly. Conquered polio. Walked on the moon. Then something happened. Science went on. And innovation.

But the breakthroughs seemed smaller. Smartphone apps, not moonwalks. We have huge challenges in this century. We need huge breakthroughs again. On energy, water, cancer, climate change. What’s in the way? How do we do it?

This hour, On Point: accomplishing really big things again.
