 AI is potentially the most powerful technology that we've ever created and it's going to create the next form of civilization. The real opportunity for AI is how we can actually help the 7 billion people that could benefit from these technologies in a practical way. We're writing the rulebook for how this technology will go into the world and we need more examples showing how artificial intelligence can create the utopias that we want to build. So the IBM Watson AI XPRIZE matters because it serves as a proof point for the AI for good dialogue. The AI XPRIZE is a five million dollar competition sponsored by IBM Watson that challenges teams from all around the world to use AI for good. Each of the competitors is actually bringing that grand challenge to the table and saying this is the biggest problem that's facing humanity and this is why my technology can solve it. We launched this prize in 2016. Since that inception the AI for good dialogue has grown a lot. It's partly because of the AI for good global summit that we partnered on but also because of this competition so it's been really fascinating to see where AI for good was three years ago and where it is now. Since every team is working on a different problem with a different AI technology we are inventing new ways of evaluating technologies towards really creating a policy that should govern the systems of the future. Judges are evaluating the teams across four different metrics, technical validity, real world impact, scalability, ethics and safety. As these AI systems are getting better it only stresses the importance of us talking about the ethics behind them and the consequences of what is happening and AI for good and the AI XPRIZE has become the mechanism to do that. We envision a future at XPRIZE where humans and machines can be used to benefit one another and machines are not here to replace us but to supplement us. Thank you.
