What Happened

British mathematician James Lighthill published a devastating critique of AI research, concluding that the field had failed to deliver on its promises. 'In no part of the field have the discoveries made so far produced the major impact that was then promised.' The report led to massive funding cuts for AI research in the UK.

Why It Mattered

Helped trigger the first AI Winter, especially in the United Kingdom. The report became one of the clearest historical examples of how inflated expectations can provoke a funding backlash when narrow successes are mistaken for general intelligence.

Perceptrons: The Book That Killed Neural Networks

Minsky and Papert published 'Perceptrons,' mathematically proving that single-layer perceptrons could not solve the XOR problem or other non-linearly separable tasks. While technically correct, the book was widely interpreted as proving neural networks were fundamentally limited — though multi-layer networks could solve these problems.

EU AI Act: First Major AI Regulation

The European Parliament approved the AI Act, the world's first comprehensive AI regulation. It established a risk-based framework: banning 'unacceptable risk' AI (social scoring, indiscriminate surveillance), heavily regulating 'high risk' applications, and requiring transparency for generative AI.

EU AI Act Enforcement Begins — With Delays

The EU AI Act's Article 50 transparency duties — chatbot disclosure, AI-content marking, and deepfake labeling — became enforceable, and the European Commission's enforcement powers over general-purpose AI providers activated. But the milestone arrived reshaped: on June 16, 2026, the European Parliament approved 'Digital Omnibus' amendments deferring most high-risk system obligations to December 2027 and August 2028 after intense industry and member-state pressure.

Backpropagation Discovered (Initially Ignored)

Paul Werbos described the backpropagation algorithm in his PhD thesis — a method for training multi-layer neural networks by propagating errors backward through the network. However, in the anti-neural-network climate of the 1970s, the work went largely unnoticed.
