The only dumb question is the question you don't ask.

The only big ideas I've ever had came from daydreaming, but modern life keeps people from daydreaming. Every moment of the day your mind is being occupied, controlled by someone else - at school, at work, watching television. Getting away from all that is really important. You need to just kick back in a chair and let your mind daydream.

I'm more interested in a world that works than what sells.

We humans are basically content with a two-dimensional world, which is what we-ve always occupied. We travel mostly on the ground, have traffic jams, parking problems , and we-d do a lot better to look up a little bit because there is that great aerial highway that-s always ready to go, you Don't have to pave it and the benefits are very great.

The problem is we don't understand the problem.

Anyone who's not interested in model airplanes must have a screw loose somewhere.

Your grandchildren will likely find it incredible - or even sinful - that you burned up a gallon of gasoline to fetch a pack of cigarettes!

Suddenly, we humans - a recently arrived species, no longer subject to the checks and balances inherent in nature - have grown in population, technology and intelligence to a position of terrible power.

We're short on wisdom we're high on technology. Where's it going to lead?
