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

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.

Big data will replace the need for 80% of all doctors

Is it 10 years, 20, 50 before we reach that tipping point where climate change becomes irreversible? Nobody can know. There's clearly a probability distribution. We need to ensure this planet, and we need to do it quickly.

Will biofuel usage require land? Absolutely, but we think the ability to use winter cover crops, degraded land, as well as using sources such as organic waste, sewage, and forest waste means that actual land usage will be limited. Just these sources can replace most of our imported oil by 2030 without touching new land.

It doesn't matter what your probability of failure is. If there's a 90% chance of failure, there's a 10% chance of changing the world.

I'm a fiscal hawk. I vote against all taxes, but I do believe the environment, and climate change, is a bigger issue than fiscal deficits are as a risk to the nation.
