What is artificial intelligence?
You hear about artificial intelligence (AI) everywhere, but what does it actually mean? A jargon-free explanation.
Artificial intelligence, usually shortened to AI, is the umbrella term for computer programs that perform tasks that would normally require human intelligence — recognizing things in a photo, writing a piece of text, answering a question, or playing a game. It's not a robot with a mind of its own, like in the movies. It's software that has learned patterns from large amounts of data.
Most AI you encounter today — ChatGPT, Google Photos recognizing faces, Netflix recommending movies — works on the same basic idea. The system has seen millions of examples during "training," and has extracted patterns from them. When you ask it something new, it uses those patterns to calculate an answer that looks logical, based on what it has seen before.
An important distinction is between AI in general and machine learning, a specific approach within AI. In machine learning, a system learns patterns from data itself, instead of a programmer typing in every rule by hand. Almost all AI that gets discussed a lot today — including language models like ChatGPT and Claude — is built using machine learning.
Why does this matter to you? Because AI increasingly helps decide things that affect you: which job listings you see, what price an insurer charges you, which news ends up at the top. Understanding that AI recognizes patterns — and therefore also inherits the mistakes and biases baked into those patterns — helps you look more critically at what an AI system puts in front of you.
