What's happening?

Early humans used spears just for hunting to find food. Then, someone realised they could be used to fight other humans too. The tool had become a weapon.

Now, some worry the same thing is happening with Artificial IntelligenceArtificial intelligence, or "AI," is the ability for a computer to think and learn. With AI, computers can perform tasks that are typically done by people, including processing language, problem-solving, and learning..

AI was made to help us and make our lives easier. But now, scientists at Oxford University worry that AI could actually harm human beings - and even wipe out every person on the planet.

Some fear that one day, humans will no longer be in charge of robots. Instead, they will be in charge of themselves.

But others say the real danger is not that AI becomes too clever and chooses to destroy us. It is that AI simply tries to be helpful.

For example, imagine an AI with a simple task: make as much money as possible for its owner. The best way to do this might be to put money into companies that make weapons - and this could start a war.

Yes! History shows us that every helpful tool becomes a weapon in the end. We need new rules to stop this happening to AI.

No! AI is new - and new things can be scary. Robots are nowhere near clever enough to take control from humans and harm us.
