Artificial intelligence is intelligence demonstrated by machines, as opposed to the natural intelligence displayed by animals including humans.
AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go).
AI provides lots of benefits to society, including increasing work efficiency, working with high accuracy, reducing the cost of training and operation, and improving processes.
However, AI also brings risks to humans. In this video, Elon Musk talks about why he has negative views about AI. He believes AI is not good for the future.
