There are no good or bad people, humans are shaped by culture.

We have more than enough to take care of everybody on earth at this time. If we have a shortage of anything, it's very easy for science to make a substitute material. There's no shortage of anything except brains in Washington.

If nations join together now, before the big collapse and share their resources, they can maintain a level of sustainability. Sustain the people that is, and not banks and businesses.

There's no such thing as designing the perfect utopian city. Everything is subject to change. There are no final frontiers.

You have to tell your children about the world they live in, about the discrepancies, about the things that don't work… So you have to bring it up with a scientific orientation so they learn to ask questions, and learn how to say the most difficult thing in the world: 'I don't know'.

It is not that people are evil or greedy. The conditions that socially support the system force us to behave in socially offensive ways.

We have the technology to build a global paradise on earth, and at the same time, we have the power to end life as we know it. I am a futurist. I cannot predict the actual future - only what it can be if we manage the earth and its resources intelligently.
