The frenemies running Microsoft and Google's AI ops have some serious history

• Microsoft's Mustafa Suleyman and Google's Demis Hassabis were childhood friends.
• In 2010 the pair cofounded DeepMind, which was later bought by Google.
• The two are on opposite sides of an AI arms race between Big Tech's oldest rivals.

Google's Demis Hassabis and Microsoft's Mustafa Suleyman first met in London when the latter was still at school.

Suleyman, the son of a taxi driver, and Hassabis, a chess child prodigy, both grew up in different parts of north London.
