Humans beat AI programs made by Google and OpenAI at an international mathematics competition, but the technology shows some "very exciting" progress.

Late last year, Dominic King and Christopher Kelly were poached by Suleyman from DeepMind to run a new AI health unit that has already developed an AI medical system that it says is four times more successful than human doctors at diagnosing complex ailments.

With the acquisition of DeepMind, Google will acquire a whole new set of technologies related to artificial intelligence. But what will it use them for, and should we be concerned?

DeepMind’s project is part of a broad effort to build artificial intelligence that can play enormously complex, three-dimensional video games, including Quake III, Dota 2 and StarCraft II.
