Personnel: David Silver at Google DeepMind (Principal Research Scientist)

NoteThe source is David Silver's own bio page and confirms he worked at DeepMind in a leadership role on reinforcement learning. However, the source indicates this is now in the past ('Until recently, I led the reinforcement learning team at DeepMind'), suggesting he is no longer in that position. The claim states he is a 'Principal Research Scientist' at 'Google DeepMind' with a startDate of 2013. The source does not specify the exact title 'Principal Research Scientist' or confirm the 2013 start date. More critically, the source's current information shows David Silver has moved on to become CEO of Ineffable Intelligence, making the record outdated. The source has been updated to reflect his current role, superseding the claimed historical position at DeepMind.
