That's our mirror. Every dip, every crash, every bubble that's burst, a testament to our brilliant stupidity. This one gave us the railroads. This one the Internet. This one the slave trade. And if we hope to do anything about saving the environment, or getting to other worlds, we'll need a bubble for that too. Everything I've ever done in my life worth anything has been done in a bubble: in a state of extreme hope and trust and stupidity.
I see a beautiful city and a brilliant people rising from this abyss. I see the lives for which I lay down my life, peaceful, useful, prosperous and happy. I see that I hold a sanctuary in their hearts, and in the hearts of their descendants, generations hence. It is a far, far better thing that I do, than I have ever done; it is a far, far better rest that I go to than I have ever known.
It's been four years. It's been the best four years. It's been wonderful, it's been a privilege to work under Steven Moffat. But I think when you gotta go, you gotta go It's sad, I'm going to miss it. I'm going to miss Comic-Con as well. It wasn't an easy decision, but I dunno, you can't play it forever. And, look, they'll get someone amazing and brilliant, and that's the great thing about the show. It continues, and it will get bigger and better. And you'll forget about me.
