like those of a human who had never seen the game would use to understand and attempt to master it.” The goal of the founders is to create a general-purpose AI that can be useful and effective for almost anything. Major venture capital firms Horizons Ventures and Founders Fund invested in the company, as well as entrepreneurs Scott Banister, Peter Thiel, and Elon Musk. Jaan Tallinn was an early investor and an adviser to the company. On 26 January 2014, Google announced the company had acquired DeepMind for $500 million, and that it had agreed to take over DeepMind Technologies. The sale to Google took place after Facebook reportedly ended negotiations with DeepMind Technologies in 2013. The company was afterwards renamed Google DeepMind and kept that name for about two years. In 2014, DeepMind received the "Company of the Year" award from Cambridge Computer Laboratory. In September 2015, DeepMind and the Royal Free NHS Trust signed their initial Information Sharing Agreement (ISA) to co-develop a clinical task management app, Streams. After Google's acquisition the company established an artificial intelligence ethics board. The ethics board for AI research remains a mystery, with both Google and DeepMind declining to reveal who sits on the board. DeepMind, together with Amazon, Google, Facebook, IBM and Microsoft, is a founding member of Partnership on AI, an organization devoted to the society-AI interface. DeepMind has opened a new unit called DeepMind Ethics and Society and focused on the ethical and societal questions raised by artificial intelligence featuring prominent philosopher Nick Bostrom as advisor. In October 2017, DeepMind launched a new research team to investigate AI ethics. In December 2019, co-founder Suleyman announced he would be leaving DeepMind to join Google, working in a policy role. Products and technologies According to the company's website, DeepMind Technologies' goal is to combine "the best techniques from machine learning and systems neuroscience to build powerful general-purpose learning algorithms". Google Research released a paper in 2016 regarding AI safety and avoiding undesirable behaviour during the AI learning process. Deepmind has also released several publications via its website. In 2017 DeepMind released GridWorld, an open-source testbed for evaluating whether an algorithm learns to disable its kill switch or otherwise exhibits certain undesirable behaviours. In July 2018, researchers from DeepMind trained one of its systems to play the computer game Quake III Arena. As of 2020, DeepMind has published over a thousand papers,
