### Key Developments in AI History

#### **1. Birth of AI (1943–1956)**
- **Early Neural Networks & Cybernetics**:  
  - Walter Pitts & Warren McCulloch (1943) pioneered artificial neural networks for logical operations.  
  - Marvin Minsky built SNARC (1951), the first neural network machine.  
- **Turing Test**: Alan Turing (1950) proposed a benchmark for machine intelligence.  
- **Game AI**: Christopher Strachey’s checkers program (1951) and Arthur Samuel’s chess advancements.  
- **Dartmouth Conference (1956)**: Coined "Artificial Intelligence"; showcased Logic Theorist (Newell & Simon).  

#### **2. Golden Age (1956–1974)**
- **Search & Reasoning**:  
  - General Problem Solver (GPS) and geometry/algebra solvers (SAINT).  
- **Natural Language Processing**:  
  - ELIZA (1966, first chatbot) and STUDENT (algebra problem solver).  
- **Microworlds**:  
  - Minsky & Papert’s "blocks world" (late 1960s) simplified complex problems.  
  - Terry Winograd’s SHRDLU (1970) executed tasks via natural language commands.  
- **Overoptimism**: Predictions like "chess champion defeat in 10 years" (Simon, 1958).  

#### **3. First AI Winter (1974–1980)**
- **Perceptrons’ Collapse**:  
  - Frank Rosenblatt’s perceptron (1958) faced criticism from Minsky & Papert (1969), halting neural network research.  
- **Technical Limits**: Weak hardware, combinatorial explosion, and lack of commonsense knowledge (Moravec’s paradox).  
- **Funding Cuts**: Lighthill Report (1973) and DARPA withdrawal stifled progress.  

#### **4. AI Boom (1980–1987)**
- **Expert Systems**:  
  - MYCIN (medical diagnosis) and XCON (computer configuration) drove commercial adoption.  
- **Neural Networks Revival**:  
  - John Hopfield (1982) and backpropagation reignited connectionist research.  
- **Fifth Generation Project**: Japan’s Prolog-based initiative (1981) aimed at general AI but failed.  

#### **5. Second AI Winter (1987–1993)**
- **Expert Systems’ Decline**: High maintenance costs and brittleness eroded trust.  
- **Hardware Market Crash**: Lisp machines became obsolete with rising PC power.  

#### **6. Modern AI (1993–Present)**
- **Milestone Successes**:  
  - Deep Blue (1997), DARPA challenges (2005–2007), IBM Watson (2011).  
- **Intelligent Agents**: Decision-theoretic models unified AI with economics/robotics.  
- **Fourth Industrial Revolution**:  
  - AI converges with IoT/cloud/big data; sparks job displacement concerns.  
  - Security challenges: Poisoning, evasion, and model inversion attacks.
