I'm a science instructor, your video host, and the architect of this program on understanding and working with AI. Of course, AI is a tool. And like any tool, first you need to know how it works, and then how to use it effectively. As a computational linguist, my main role has been guiding the direction and assuring technical accuracy. You're going to love this program. It's full of insightful and useful information, but, mostly, it's full of heart and level-headed optimism. As a cultural anthropologist, my role has been developing the later chapters where we dig into the many social impacts of AI. Thank you for taking this program on how AI works and how we can work with AI to make this world a better place.
