We'll go back to the moon by not learning anything new.

Testing leads to failure, and failure leads to understanding.

We need affordable space travel to inspire our youth, to let them know that they can experience their dreams, can set significant goals and be in a position to lead all of us to future progress in exploration, discovery and fun. Thanks to the X Prize for the inspiration.

In the coming era of manned space exploration by the private sector, market forces will spur development and yield new, low-cost space technologies. If the history of private aviation is any guide, private development efforts will be safer, too.

We may think we live in a digital age. But there are some things technology will never replace.

I'm not really part of the Internet world, my age a factor in that and a lack of interest in sharing with so many, so little, so much, so often.

If it's just me on stage telling stories for, like, an hour, that's great. That's fine. But like a sandcastle on the beach, it gets washed away at night. It's so much more powerful if we can all share our narratives and doorstep moments and make us feel a little less alone. I'm just trying to use social media and new media as a way to capture that.

The Internet didn't become usable until Netscape because that gave the average person a user interface that was intuitive, simple, friendly - this made it accessible.
