Foundations Before the Name: The Early Sparks (1930s–1955)

In 1950, Alan Turing asked whether machines can think, proposing the imitation game as a practical test. His vision reframed intelligence as behavior rather than essence, inviting engineers to build systems that perform convincingly. What would your own test for machine intelligence look like today?

The Dartmouth Summer and Symbolic Dreams (1956–1969)

John McCarthy, Marvin Minsky, Claude Shannon, and others gathered with confidence that intelligence could be precisely described and simulated. Their proposal radiated optimism, catalyzing decades of research. If you had attended, which subproblem would you have championed first and why?

The Dartmouth Summer and Symbolic Dreams (1956–1969)

Newell and Simon’s programs tackled puzzles through search and symbolic representations, offering a template for problem-solving machinery. Though brittle, they revealed how structure guides reasoning. Share a modern task where symbolic scaffolding still helps your models compete or cooperate with learned representations.

Shakey’s Cautious Steps

SRI’s Shakey navigated rooms using planning and a world model, turning abstract reasoning into careful motion. Every wobble taught researchers about perception, action, and uncertainty. If you were mentoring Shakey today, what sensors and algorithms would you add to accelerate its learning curve?

Perceptrons and a Pause

Minsky and Papert highlighted perceptron limits, particularly for tasks requiring layered abstractions. Momentum slowed as expectations dimmed. Yet the critique also challenged researchers to imagine deeper architectures. Tell us how you explain that crucial detour when teaching newcomers about neural network history.

Expert Systems Boom and Bust

Rule-driven expert systems like MYCIN and XCON delivered business value, but knowledge engineering proved costly and brittle. As domain complexity grew, maintenance strained budgets. What lessons from that cycle guide your approach to balancing symbolic rules with data-driven learning today?

From Rules to Probabilities

Bayesian networks, hidden Markov models, and graphical approaches reframed intelligence under uncertainty. Instead of brittle logic, systems reasoned about noisy observations and latent causes. Share your favorite example where probabilistic thinking simplified a messy problem and unlocked a robust, interpretable solution.

Deep Blue vs Kasparov

IBM’s Deep Blue defeated Garry Kasparov in 1997 using search, evaluation heuristics, and specialized hardware. It was not learning as we know it today, but it proved computation could outplay a world champion. How did that match reshape public expectations for the timeline’s future?

The Internet Floods the Datasets

Web-scale text, images, and user behavior powered advancements from the Netflix Prize to early large corpora. ImageNet’s curation set the stage for new representation learning. Which dataset most transformed your practice, and how do you manage its biases across evolving applications?

Deep Learning Breakthroughs and the New Wave (2012–2019)

In 2012, AlexNet’s convolutional network slashed ImageNet error using GPUs, ReLUs, and data augmentation. Feature engineering ceded ground to learned hierarchies. Tell us how that watershed moment changed your workflow, from experimentation speed to the architectures you trust for production.

Transformers replaced recurrent bottlenecks with attention, scaling context and enabling pretraining. From translation to BERT’s masked tokens, transferable language understanding surged. Which transformer insight most surprises newcomers you mentor, and how do you illustrate it with a clean, compelling example?

AlphaGo’s 2016 triumph over Lee Sedol, especially the startling move 37, showed how learned policies and search could invent unconventional strategies. Humans studied the game anew. Share a moment when an AI system taught you a fresh angle on a familiar domain.
