What I really wanted was for everybody to have their genome and, ideally, everybody to share their genome, and for that, we needed to bring the price way down.

We will have to make a decision, as we go into new environments outside of earth, whether we want to drag along with us all our pathogens. We can, or we can't - it's up to us - but I consider that part of genome engineering is how we interact with the huge part of our genome which is our microbiome.

I will make the argument that we are poorly adapted to our current environment. I mean, we did not evolve to sit all day and be exposed to giant amounts of really tasty food.

My laboratory and my obsession is about safety and building/engineering safety. It's not just a matter of saying we want the world to be safer; we have to create technology.

We have a love affair with the idea of the 'natural,' even though we, as a species, are about as unnatural as you can imagine.

I think my original inspiration came from just natural curiosity about science and math and biology. In particular, I would say that, as I matured, it became more a feeling of trying to avoid the waste that occurs in the world where we have 6.5 billion minds. If you're a computer scientist, you can think of them as supercomputers.

When something like personal genomics or synthetic biology suddenly appears - it seems to suddenly appear - we might have been working on it for 30 years, but it seems to come out of nowhere. Then you need strategies for engaging a lot of people and thinking about where it will be going in the next few months or few years.

In my lab, we are constantly asking, 'What's the utility of this pure science that we're doing? Let's nudge it a little bit in a direction where people can connect to it and have some fun and/or help some very serious problems they have.'

Most people are excited about themselves. Personal genome will deliver for inexpensively something about science to which you can relate. Just like computers are becoming something to which you can relate. It should be even easier to relate to your own biology, and I hope that will be one of the ways we get broader literacy in science.

We have the ability to completely change our environment to go... to take on... to inherit, in a certain sense, things far beyond our DNA, and that's inheritable. And we can see evolution in action as our ideas evolve and undergo a kind of Darwinian selection not at the DNA level. And we can go off into space.
