I was listening to a recent TED Talks podcast featuring Jason Pontin. Pontin is the editor in chief and publisher of MIT Technology Review. The topic: Can technology solve our big problems. He starts out describing Buzz Aldrin's descent out of Apollo 11 on July 21, 1969. He notes that NASA spent $180 billion in today's funds and it was a collaboration of 20,000 companies, universities and government agencies. Why did the United States do this? The short answer: In 1962 John F. Kennedy stirred a nation by saying "We choose to go to the moon not because [it is] easy, but because [it is] hard."
