Rohan and Kamal talk to artificial intelligence expert, neuroscientist and entrepreneur Demis Hassabis. A former chess child prodigy, Demis is chief executive of DeepMind, the artificial intelligence business bought by Google for £400m only three years after it had started. But previously Demis had another company, which had failed. In this podcast he talks about lessons learnt from that experience; the dangers of being over idealistic, burn out and knowing when to cut your losses.
