I don't worry. It's just not in my nature, really.

There's a big tendency to gravitate toward a closed and proprietary approach too easily.

I think that reality exists and that it's knowable.

When I was growing up in Huntsville, Alabama, this is where the space and rocket center was. This is where all of the German rocket scientists came after war and started designing rockets for NASA, for the moon landing and all that.

It just didn't occur to me, sitting at my computer, that I would end up travelling all over the world.

I have always liked the idea of going to print because a big part of what we are about is to disseminate knowledge throughout the world and not just to people who have broadband.

What can we put into the hands of people under oppressive regimes to help them? For me, a big part of it is information, knowledge - the ability to defeat propaganda by understanding it.
