The only way you multiply resources is with technology. To really affect poverty, energy, health, education, or anything else - there is no other way.

Your cellphone has 10 sensors, and your car has 400. But your body has none - that's going to change.

In my view, it’s irreverence, foolish confidence and naivety combined with persistence, open mindedness and a continual ability to learn that created Facebook, Google, Yahoo, eBay, Microsoft, Apple, Juniper, AOL, Sun Microsystems and others.

Now it will take a long time to scale biofuels, but I'm the only one in the world forecasting oil dropping in price to $35 a barrel by 2030. I'll put it on the record: Oil will not be able to compete with cellulosic biofuels. If you do it from food, the food will get so expensive you can't make fuel out of it.

There's no doubt in my mind over the next 25 years how we drive, how we build our houses, how we fly, how we build our buildings, will all change.

Imagine the world of mobile based on Nokia and Motorola if Apple had not been restarted by a missionary entrepreneur named Steve Jobs who cared more for his vision than being tactical and financial.

We don't need a fuel that's cleaner, we need a fuel that happens to be cleaner, but is half the price of oil.
