Garry Kasparov was a guest at Google last week. He discussed his new book “Deep Thinking,” his 1997 match (and loss) against IBM’s Deep Blue and his thoughts on the future of artificial intelligence. The event was moderated by the CEO of DeepMind, Demis Hassabis.

For those who don’t know the backstory, Kasparov’s 1997 chess match against the IBM supercomputer Deep Blue was seen as a watershed moment in the history of technology. It was the first defeat of a reigning world chess champion to a computer under tournament conditions and Kasparov became the symbol of man’s fight against the machines.

For more on the future of artificial intelligence, see this short opinion piece by Hassabis in the FT.
