R1/XCON: Expert Systems Go Corporate

What Happened

R1 (later XCON) was deployed at DEC to configure VAX computer systems. It saved DEC an estimated $40 million per year. This commercial success sparked a gold rush: by 1985, companies were spending over $1 billion per year on expert systems.

Why It Mattered

Proved AI could deliver real business value. Launched the expert systems industry and revived AI funding — but also set up the next crash.

Hopfield Networks: Physics Meets Neural Networks

Physicist John Hopfield showed that a type of recurrent neural network could serve as content-addressable memory, using concepts from statistical physics. The network would converge to stable states that could store and retrieve patterns — connecting neuroscience, physics, and computation.

Backpropagation Rediscovered

Rumelhart, Hinton, and Williams published 'Learning Representations by Back-propagating Errors' in Nature, demonstrating that backpropagation could train multi-layer neural networks effectively. The same year, the PDP (Parallel Distributed Processing) group published their influential two-volume work on connectionism.
