Of course the Silicon Valley is unique and Berlin is not yet comparable. But of all the different cities that are building a startup infrastructure, Berlin is the one with the most similar energy.

The thing I really care about is the mission, making the world open.

AI systems will enable doctors to diagnose diseases and treat people better, so blocking that progress is probably one of the worst things you can do for making the world better.

My goal was never to just create a company. A lot of people misinterpret that, as if I don't care about revenue or profit or any of those things. But what not being just a company means to me is not being just that - building something that actually makes a really big change in the world.

I think people tend to be worried about every new technology that comes along.

Berlin is one of my favorite cities in the world. I feel like the energy is very youthful. It has such an important history, including its recent history of unification.

If you actually do something you love it's a lot easier and takes on a lot more purpose.
