From the Dartmouth proposal to Jensen Huang’s AGI remark: a 70-year history of AI booms, winters and shifting definitions
MarsBit revisits the 70-year arc of artificial intelligence through a current flashpoint: Jensen Huang’s remark on Nvidia’s August 26, 2026 earnings call that, "for a lot of tasks, we can say that we have achieved AGI." The article does not treat that line as settled fact. Instead, it uses the debate around it to trace AI from the 1955 Dartmouth proposal, where John McCarthy, Marvin Minsky, Nathaniel Rochester and Claude Shannon outlined a summer project built on the idea that learning and intelligence could, in principle, be described precisely enough for a machine to simulate them. The piece walks through the field’s early optimism, the perceptron era, symbolic AI, the Lighthill report, expert systems, the two AI winters, and the period when researchers avoided the term "AI" altogether in favor of machine learning, pattern recognition and related labels. It then follows the buildup to the deep learning turn, including ImageNet, AlexNet, DeepMind’s reinforcement learning work, AlphaGo, and the Transformer paper "Attention Is All You Need," before moving into BERT, GPT, scaling laws, Chinchilla, diffusion models and ChatGPT. The central argument is that AI history keeps repeating a few patterns: promises outrun capabilities, definitions keep moving, and methods built to scale with compute often overtake systems packed with hand-crafted human knowledge. On that basis, the question of whether AGI has been achieved remains unresolved not only because capability is contested, but because the term itself has never had a fixed, falsifiable definition.
