I keep running into (understandably) confused takes on "If the CEOs of these companies really believe AI might kill everyone... why would they start a company to build AI?" and rather than try to explain with nuance in words:
My main issue is that Meta AI was founded in 2013 as Facebook AI Research, before OpenAI. Two of the best-known(?) Chinese labs, DeepSeek and Moonshot AI, were founded in 2023, but I doubt think that it was Anthropic who inspired them. Maybe it was the ChatGPT moment? Alibaba's Qwen had its architecture based on one of Meta's Llamas. But I don't quite understand what motivated Musk to found xAI.
