Everyone agrees that innovation is thekey to solving the many challenges we face as a country from health care toeducation to the environment, and is fundamental to restoring economic growth andprosperity. But I would put it a slightly different way. We must find a way torebuild the "innovation infrastructure" in this county.

The problem is not that Americans aren′ tas inherently innovative as ever we are. And the level of interest amongAmericans in the process of innovation--determining the best recipes to make ithappen--has been skyrocketing over the past few years. For example, the numberof times the word "innovation" appeared in Google news stores hasincreased by approximately five from Obama′s inauguration to today. Google theterm "innovation" and you′ll get 342 million hits, approximately halfthe 676 million hits that "Obama" generates. And according to hashtags org, innovation is trending about the same rate as deficit.

Our problem is that the system is failingour citizens. The "seed corn" of innovation-creative ideas ...fundamental rate it was before. Viable "seed com" requires aninnovation infrastructure in which bright minds are provided the resources andfreedom to create and invent according to their passions and curiosities, totake bold risks, and even to fail. Such an innovation infrastructure thrived inthe U.S. in the late 20th century as a collaboration that put Americans on themoon, and to the personal computer, the Internet, and the era of genomicmedicine.

Americans are ready and willing to embracethe goal of once again leading the world in innovation. This could be the moonshot for the next decade that unifies our country. However, we are at atremendous disadvantage unless the innovation infrastructure of this country isrebuilt. This requires a new collaboration among government, industry andacademia-one that is suited to the challenges and opportunities of the digitalage, and that restores the bold risk taking
