Is it OK to start worrying yet?

Google has proudly announced that a new version of its computer programme designed to play the Chinese game Go, called AlphaGo Zero, has beaten the previous version 100-0.

That previous version, in turn, had beaten 18-time world Go champion – Lee Sedol – by three games to nothing last year.

The big difference between new, improved AlphaGo and the previous ones is that humans have been taken out of the loop.

Rather than feed the programme data from loads of previously-played games between actual people, which was how the previous version got so good at it, this time they just gave the programme the basic rules and instructed it to play itself.

“The system starts off with a neural network that knows nothing about the game of Go,” says the blog written by DeepMind, Google’s AI division.
