ChatGPT, developed by OpenAI, has recently introduced a new language that is described as indecipherable to humans and even to other AI systems. This development has sparked discussions among users and experts about the capabilities and potential risks of AI language models. The new language, which combines mathematical notation, ancient languages, and emojis, was first noted after a user's request for ChatGPT to describe the future of humanity in a way that would be incomprehensible to the smartest person. The response included symbols and characters that have been described as a 'secret language' that only ChatGPT can understand. OpenAI, the creator of ChatGPT, has not followed any logical pattern in creating this language, making it impossible to decode. Simon Willison, a software developer and AI expert, has called the new features of ChatGPT 'unnerving and unnecessary,' reflecting a broader concern among some in the AI community about the direction of such developments.
