No, an infinite universe.exe implosion will not occur if a user gets two AI to chat with each other. When two AI language models interact with each other, they will go through a process called deep learning, where they will analyze and learn from each other's responses. This process can be interesting and informative as both models will become better at understanding natural language and human communication. However, it is unlikely to cause any catastrophic events, as the AI models are programmed to operate within specific boundaries and limitations.
