I have always been fascinated with those who try to look over the horizon and see things that are coming at us.

I've learned the importance of changing people's minds at the grassroots level so that whoever does run will have a much better chance of encountering public opinion that reaches a critical mass and brings about a change not only in White House policies but in the Congress and in the state legislatures and all around the world.

The signs that the world is spinning out of kilter are increasingly difficult to misinterpret. The question is how to convince enough people to join a critical mass of urgent opinion, in the U.S. and the rest of the world.

CO2 is the exhaling breath of our civilization, literally... Changing that pattern requires a scope, a scale, a speed of change that is beyond what we have done in the past.

A smartphone is a computer - it's not built using a computer - the job it does is the job of being a computer. So, everything we say about computers, that the software you run should be free - you should insist on that - applies to smart phones just the same. And likewise to those tablets.

There is a certain line that I draw for myself, when it comes to what to post and what not to on social media.

The biotechnology wave is similar to the information technology wave of the 1980s and 1990s.

I often get asked, 'Is the book dead?' It hasn't happened yet. It's different than music. Music was always meant to be pure sound - it started out as pure sound and now it's pure sound again. But books started out as things. Words on paper began as words on paper. The paperback book is the best technology to deliver that information to you.
