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.

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

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.

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

The problem is we don't understand the problem.

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