Welcome to Practical AI. This is class one of forty, and the goal of the entire course is simple: by the end, you will have AI as part of your daily routine. Not as a hobby, not as a curiosity, but as a tool you actually reach for the way you reach for a calculator or a search engine. The course assumes you are starting from zero. If you have heard of ChatGPT but never used it, or you have used it once and felt confused, you are in exactly the right place. Today's class is the foundation. We will answer the four questions that confuse most beginners. What is AI actually? What is it good at? What is it bad at? And why is it worth learning? You will leave this lesson with a working mental model — not a technical one, but the simple, useful one that makes everything else click. The tool is genuinely powerful and genuinely easy to use once you understand what it is. Most adults try it once, get a mediocre result, and give up. That is a mistake. The tool rewards a few hours of structured learning with thousands of hours of saved time over the rest of your life. So let us start.
