The document summarizes the evolution of artificial intelligence (AI) from the 1950s to the present. It discusses three waves of AI development: handcrafted knowledge in the early period, statistical learning from the 1960s to 1980s, and contextual adaptation from the 1990s onward. Recent advances are driven by increased computing power, data availability, and new algorithms. Deep learning is increasingly important and applications include voice control, natural language processing, and computer vision. While AI has great potential, a lack of talent and data is creating a bifurcated ecosystem with large tech firms at the top.
