I'm Astro Teller. I'm the captain of moonshots. I run the moonshot factory called X at alphabet. Why are you here? What's your focus here? So X works on lots of different moonshots. At this point more than half of all of the moonshots we're exploring are in the climate space. How can AI help us? I would say that AI and machine learning first, it's like electricity. It's going to be everywhere and it will participate in everything. But let me give you two very concrete ways it can help with sort of climate mitigation and climate adaptation. Machine learning can act as agents for us in the world. So if you can tell your car or your refrigerator, hey don't charge yourself when electricity is very expensive, that acting on your behalf, that's artificial intelligence and machine learning, helping you to help the planet.
