In 2012, Google acquired DNNResearch, a startup founded by "the father of deep learning" Hinton and others, for $44 million in a secret auction. This marked Google's official entry into the competition for AI talent. Subsequently, Google spent $6.5 billion to acquire the British startup DeepMind. With the addition of top talents like Geoffrey Hinton, Google quickly established a leading position in AI technology. Facebook, on the other hand, recruited Yann LeCun to help manage its artificial intelligence laboratory, also securing a significant position in the ecosystem. The establishment of OpenAI led many researchers to leave the laboratories of tech companies. Finally, Google adjusted its strategy and announced it would no longer publicly disclose its latest research findings.
