As Stewart Brand (co-founder of Emeryville's Global Business Network) likes to say, "Information lasts forever. Digital information lasts forever or for five years, whichever comes first." There are examples everywhere. The tapes from the original Viking landers that went to Mars are at (NASA's) Jet Propulsion Laboratory, but there is no machine that can read the tapes.

We invent our technologies and then we turn around and use our technologies to reinvent ourselves as individuals, communities and cultures.

The best way to let people go is to let them know when they're hired that it's an uncertain environment and that their job is always at risk and even if you let them go, it's not that you don't love them.

I think companies over the last 10 years have done a very bad job of explaining to their employees what the intrinsic risks are. All I know is, if you wait until you let the employee go to deal with the issue of how do you communicate to the employee about being let go, it's too late to do anything.

People were touchingly naive at the dawn of the Internet revolution when they said the Internet will route around censorship the way it routes around damage. With any revolution, the establishment catches up and figures out how to screw it up. The answer is to keep technology advancing fast enough so that those who would try to control it can't. It's up to people to defend what they care about. We shouldn't be complacent that this stuff is going to be a force for good.

There is reason to be scared. Look at what has happened with fundamentalism - this is a reaction against modernity. It happens to be cloaked in religion, but these are people saying enough is enough. It's happened again and again through history. The good news is that modernism has always won.

It turns out it takes 30 years for a new idea to seep into the culture. Technology does not drive change. It is our collective response to the options and opportunities presented by technology that drives change.
