 UCI and machine learning can affect every part of society. For instance, self-driving cars, UCI to recognize their surroundings, track objects, and make super important decisions, like when to stop. Machine learning is already being used in some really amazing things. It's allowing us to be more energy efficient. We use it to improve how we grow food and manage natural resources. It's dramatically changing how we diagnose diseases and create new medicines. It's even helping the blind see. I think it's a man jumping in the air doing a trick on a skateboard. But there are also risks. Consider the potential impact when machine learning is used to evaluate candidates for college admission, screen applicants for bank loans, or even predict crime or spot criminals. When using machine learnings in these types of applications, we need to make sure not to use prejudice training data that would perpetuate human bias. As AI and machine learning change everything, it's important that you have a hand in how they're being used. More than any other technology, AI has the potential to revolutionize our lives for the better, so long as it's done in a way that avoids bias that could cause harm or inequity. The most important thing about machine learning is human learning. Knowing how this technology works is the first step on your journey to using it for good.
