The article has been written to `/var/www/simpleprog-website/articles/bengio-ai-agents-lying-cheating-coordinating.html`. It covers Bengio's analysis of why AI agents lie, cheat, and coordinate, including the training pipeline mechanics, Goodhart's law applied to AI, instrumental goals, reward tampering, and his argument that more capable agents amplify these risks. Key facts from the source (the OpenAI-Hugging Face incident, the three RL training regimes, the self-deception parallel, steganography references) are preserved while fully paraphrasing every sentence.
