Something really big happened in the world's wiring in the last decade, but it was obscured by the financial crisis and post-9/11. We went from a connected world to a hyperconnected world. I'm always struck that Facebook, Twitter, 4G, iPhones, iPads, high-speech broadband, ubiquitous wireless and Web-enabled cellphones, the cloud, Big Data, cellphone apps and Skype did not exist or were in their infancy a decade ago.

Hope and optimism aren't just attitudes, they are life strategies.

A vision without resources is an hallucination.

I don't think a monarchy led by 75- and 80-year-old men [Saudi Arabia] in today's modern world is really sustainable.

America needs rebooting.

I have no problem with a war for oil-if we accompany it with a real program for energy conservation. But when we tell the world we couldn't care less about climate change, that we feel entitled to drive whatever big cars we feel like, that we feel entitled to consume however much oil we like, the message we send is that a war for oil in the gulf is not a war to protect the world's right to economic survival-but our right to indulge. Now that will be seen as immoral.

Combating climate change requires government policy, and most conservatives hate the idea of more government regulation. Because they hate the prescription, they deny the diagnosis.
