Yann LeCun, Meta's chief scientist, pointed directly to the problems in "some circles" in Silicon Valley in a post on his LinkedIn account yesterday: "In some Silicon Valley circles, a common symptom is: a false sense of superiority. Symptoms in the early stages are: believing that your small circle has a monopoly on good ideas. Symptoms in the late stages are: believing that innovation elsewhere is obtained through cheating." Yang Likun, who has previously praised the DeepSeek R1 model, said that the biggest lesson from its success is the importance of keeping AI models open-source so that everyone can benefit from it.
