What AI actually is (and isn't)

If you've found AI confusing, that's not a failing on your part. The loudest voices are either selling you a miracle or warning you of the end of work. Both are selling fear. This hour is the calm version.

The one-sentence definition

The AI most businesses mean today is a tool that has read an enormous amount of text and learned to predict what words, in what order, tend to answer a request well. That's it. It's a very capable assistant for language and patterns — not a mind, and not a colleague with judgement.

What it is not

• It is not conscious, and it does not 'want' anything.
• It does not look things up the way you do — it predicts, which is why it can invent a plausible-sounding fact.
• It is not a single product. 'AI' covers chat assistants, transcription, image tools, and more — each good at different jobs.

Hold on to the assistant idea. Everything else in this course is about using a fast, fallible assistant well — getting the upside without the risk.
