I think it’s more modeling. I never bring in my children and say, “Listen, these are the values you should follow in life.” I think it’s a modeling by my wife and me. I think we give them a good life. They saw how we go through life: a difficult time, a hard time, good time. I am very happy. I think they are good kids. If I have hope, it’s because I look at my children.

Being a father teaches you very quickly that you are not the center of your own universe. That’s one of the gifts of having to wipe poop!

My daughters are something, and they just surprise and enchant and impress me more and more every single day as they grow up. And so these days, when we talk, we talk as parent to child, but also we learn from them.

My greatest joy as a father is to see our children growing up and growing independent, and becoming brilliant ... But also every now and then needing me for something and remembering where I can fit into the world. And one of the great joys you realize is that you need them ... You work for their smile. You work for their joy.

I’m proud any time that I see a toxic chemical process, something that produces toxic waste or requires precious metals, which have to be mined at terrible environmental degradation costs — I’m proud when I see that replaced with a clean, efficient biological process that doesn’t produce those things. And we have to do that a million times over in order to move away from our addiction to this old-fashioned chemistry that we do.

I realized I took ideas from philosophers like Dan Dennett. I took ideas from evolutionary biologists like John Maynard Smith. I took ideas from people who were trying to implement evolution for things like RNA, so people like Jerry Joyce at Scripps. I took ideas from lots of people who could explain their ideas well, so I’ve been influenced by many. I’ve built my ideas on the contributions of many. And, of course, that’s what evolution does. It mutates and recombines what’s already there. Nothing comes out of nothing, right? It all comes on the back of what was there.
