The TECHNOLOGIES that raise the fewest ETHICAL PROBLEMS are those that WORK on a human scale, brightening the lives of INDIVIDUAL people.

Chemical propulsion is obsolete to GO anywhere other than the moon. Three DAYS - that's acceptable. But for Mars, we need propulsion technologies to get us there in, say, 60 days - then SPEND whatever length of TIME we WANT to spend and return when we want to come home.

Green REVOLUTION technologies are scale-neutral but not resource-neutral. Inputs are needed for OUTPUT; therefore market-purchased inputs become IMPORTANT in providing SOIL and plant healthcare for higher YIELDS.

Now, a lot of what we are doing right now, quite frankly, is because of what happened on Christmas. Many of the THINGS were kind of in the works. We were already planning, for EXAMPLE, the purchase and deployment of ADVANCED imaging technology. You call them body scanners. We call them AITs (Advanced Imaging TECHNOLOGIES).

We need to ensure our men and women in uniform are equipped with the very best money can buy. We also have to make sure critical military technologies are developed in AMERICA and that the U.S. defense manufacturing base REMAINS HEALTHY and STRONG.

If you look at the history of communication, NEW technologies like the phone and e-mail didn't just let people do things faster; it fundamentally changed the scope of the kinds of PROJECTS people DARED to take on.

We want to build technology that everybody LOVES using, and that affects everyone. We want to create beautiful, intuitive services and TECHNOLOGIES that are so INCREDIBLY useful that people USE them twice a day. Like they use a toothbrush. There aren't that many things people use twice a day.

Over the long TERM, we should develop and implement new TECHNOLOGIES to capture and store coal's CARBON emissions. We also must make our electric GRID more resilient.

One of our most promising TECHNOLOGIES is Super Cruise, which is the WORKING name for an innovative system coming to Cadillac in the 2016 TIME frame. It will allow you to DRIVE on the highway without touching the wheel or pedals, both at SPEED and in stop-and-go driving.

I love USING the latest TECHNOLOGIES to make LIFE more efficient, but I don't want to advocate that technology replaces the NEED to get TOGETHER and enjoy human connections with people.

The most IMPORTANT innovators often don't need any TECHNOLOGIES - just imagination and acute sensitivity to people's NEEDS.

Many new TECHNOLOGIES COME with a PROMISE to change the world, but the world refuses to cooperate.

We've been surrounded by images of space our whole lives, from the speculative images of science fiction to the inspirational visions of artists to the INCREASINGLY beautiful pictures made possible by COMPLEX TECHNOLOGIES. But whilst we have an overwhelmingly vivid VISUAL UNDERSTANDING of space, we have no sense of what space sounds like.
