CONCEPTS & TURNING POINTS / 2 MIN READ
Cybernetics and the Birth of the AI Field (1940s–1950s)
On this page
The term “artificial intelligence” was coined in 1956, but its intellectual roots include cybernetics, control theory, and Turing’s question. This sub-article expands Section 2 of History.
Cybernetics
- Norbert Wiener’s Cybernetics (1948) framed control and communication in animals and machines.
- Core concepts: feedback loops, homeostasis, information, and purpose.
- Cybernetics influenced robotics, control theory, and early AI.
Turing’s Question
- In Computing Machinery and Intelligence (1950), Turing asked “Can machines think?” and introduced the Turing test.
- He predicted machines would eventually play chess and converse, and sketched learning by “reward and punishment.”
The Dartmouth Workshop (1956)
- Organized by McCarthy, Minsky, Rochester, and Shannon.
- Coined artificial intelligence and defined the field’s founding goal: to simulate every aspect of learning and intelligence.
Early Programs
- Logic Theorist (Newell & Simon, 1956) proved theorems in propositional logic.
- General Problem Solver (1957) applied means–ends analysis to diverse problems.
- Samuel’s checkers program (1959) pioneered machine learning via self-play.
Why It Matters
The 1950s established AI as a distinct field, defined its central question, and produced the first programs that reasoned, learned, and played games.
