Artificial intelligence

● Core

The broad goal of getting machines to do things that used to need a human mind.

Think of it like

“Vehicle” to “car” — AI is the whole category; today’s chatbots are one make and model inside it.

Example

A chess engine, a spam filter, and a chatbot are all “AI,” which is why the word explains almost nothing on its own.

How it actually works

AI is the umbrella term for machines performing cognitive-seeming tasks. It stretches from hand-coded rule systems to modern learned models. Most of what people mean by “AI” today is a narrow slice: large models trained on data, not anything with general understanding.

For product teams

Useful as a banner, useless as a spec — always ask which technique someone actually means.

For engineers

The field encompassing symbolic systems, classical ML, and deep learning aimed at intelligent behavior.
