My advice is don't use technology primarily to lower costs. Use technology to create new, effective ways of touching the market and creating new businesses and if you do that right, the cost savings will come.

I would say digital technology probably doesn't have much impact on us so far. We've seen photographs of people from when they are alive. We see home movies. We have videotapes now and e-mails. When it's going to get interesting is in massively multiplayer online games where you have avatars (online personas). You could actually create an avatar that's semi-autonomous. It could do things for you while you get off the game to run the rest of your life.

Never mistake a clearer view for a short distance just because the technology looks like it's about to arrive in the very near future. Chances are there will be some surprises and in the long run even the most expected of futures tends to arrive late and in completely unexpected ways.

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.

When everybody else is in a down market is focusing on what they're doing wrong, instead focus on what you should be doing differently, it may be that what you did in the past was perfectly right. It is possible to do all the right things in business and still have a business crisis because of what's happening in the external environment. And if you start focusing on mistakes only, you're going to miss opportunities.

Think about reading: Today, parents would love it if their kids read books more because the parents understand the books. Just over 100 years ago, parents were upset because their kids were reading dime-store novels. Parents would say, "I don't want you inside reading anymore. Get outside and play." I guarantee you, in 50 years or so, parents are going to say, "You're not going outside to play until you finish that video game."

Responding to climate change will become the obsession of the next decade in much the same way terrorism was this decade's obsession.
