Artificial intelligence

Artificial intelligence (AI) is a computer system that does tasks we normally think need human intelligence: recognising speech or faces, translating, predicting, or writing text. AI isn't magic, and it isn't alive. It is software that finds patterns in huge amounts of data.

Rules or learning?

Ordinary programs follow rules a programmer wrote: "IF the mark is 50 or more, print Pass." Many AI systems instead learn their own rules from examples. Show a system thousands of emails marked "spam" or "not spam", and it learns what spam usually looks like, without anyone writing every rule.

AI around you

You probably use AI every day: voice typing on your phone (including in Kiswahili), the spam folder in email, maps that predict traffic on Thika Road, apps that suggest the next video, face unlock, and translation apps. Banks and mobile-money services also use AI to flag unusual transactions that might be fraud.

Narrow AI

Today's AI is narrow: each system is good at one kind of task. A chess AI can't drive a car, and a translation app can't diagnose a sick goat. Films often show AI that thinks like a person about everything, but that doesn't exist.

What AI can't do

AI can be confidently wrong. It doesn't understand the world the way you do, it can repeat unfairness hidden in its data, and it has no common sense outside its training. That's why people must check its work, especially for anything important like health, money or exams.

Key points

  • Artificial intelligence is software that finds patterns in lots of data.
  • Ordinary programs follow written rules; AI often learns rules from examples.
  • Voice typing, spam filters, maps and video suggestions all use AI.
  • Today's AI is narrow: each system does one kind of task.
  • AI can be confidently wrong, so people must check its work.
  • AI is a tool made by people, not a living thing.

Try it for real: AI spotter

  • For one day, list every time you or your family use something that might be AI (phone, TV, apps, shops).
  • Pick one and ask: what examples might it have learned from?
