One area where I think we are especially distinctive is failure. I believe we are the best place in the world to fail (we have plenty of practice!), and failure and invention are inseparable twins. To invent you have to experiment, and if you know in advance that it's going to work, it's not an experiment. Most large organizations embrace the idea of invention but are not willing to suffer the string of failed experiments necessary to get there.

I like going to Burning Man, for example. An environment where people can try new things. I think as technologists we should have some safe places where we can try out new things and figure out the effect on society. What's the effect on people, without having to deploy it to the whole world.

People were wondering, "How do you even do food e-commerce? Are we going to be dropping strawberries on somebody's doorstep? It doesn't feel like we're going to be doing that". But what we believed is that in the US pickup might work. So we started in California and then Denver, and a team started working to put everything in place to do grocery pickup and in the beginning we even had a separate app. It was an orange online grocery app.

If you have a really good idea, stick to it, but be flexible on how you get there. Be stubborn on your vision but flexible on the details... People who are right a lot change their mind... They have the same data set that they had at the beginning, but they wake up, and they re-analyze things all the time, and they come to a new conclusion, and then they change their mind.

There is no map, and charting a path ahead will not be easy. We will need to invent, which means we will need to experiment.

Because, you know, resilience - if you think of it in terms of the Gold Rush, then you'd be pretty depressed right now because the lastnugget of gold would be gone. But the good thing is, with innovation, there isn't a last nugget. Every new thing creates two new questions and two new opportunities.
