Artificial Intelligence(AI)

Artificial Intelligence is a broad term for computer systems that can carry out tasks we normally associate with human thinking. That covers a lot of ground: spotting a face in a photo, suggesting the next word as you type, translating between languages, or answering a question in plain English.

It helps to know that “AI” is an umbrella. Underneath it sit many different approaches and tools. The kind most people have met recently is the chatbot that writes and talks back to you, but a spam filter and a satnav route-planner are forms of AI too. They are quieter about it.

When you hear “AI” in the news or in this guide, it almost always means the modern, conversational kind: tools built on a large language model that you can ask for help the way you would ask a knowledgeable colleague. That is the sense we will use most often.

One thing worth keeping in mind: AI is genuinely capable, but it does not “know” things the way a person does. It is very good at producing likely, useful answers, and it can also be confidently wrong. Learning where it shines and where it slips is a big part of using it well, and it is exactly what the rest of these guides will help you with.
