The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.

Many of the technologies that are now racing ahead most rapidly, replacing human workers in factories and offices with machines, making stockholders richer and workers poorer, are indeed tending to accentuate the existing inequalities in the distribution of wealth.

The marketplace judges technologies by their practical effectiveness, by whether they succeed or fail to do the job they are designed to do.

There is a great satisfaction in building good tools for other people to use.

I hate to travel.

My writing is a combination of three elements. The first is travel: not travel like a tourist, but travel as exploration. The second is reading literature on the subject. The third is reflection.

This country has been very good to us, every time we have a fight in the UFC it's incredible here in Australia and we want to go everywhere. We want to travel everywhere and continue to do fights all over the country.

If I had to define my philosophy, it would be about exploration, a journey, a story-telling.
