Artificial intelligence (AI) is the science of training systems to emulate human tasks through learning and automation. It has evolved from neural networks in the 1950s-1970s to today's machine learning, deep learning, and cognitive systems. AI can be both a threat and opportunity - it can help businesses gain competitive advantages through increased efficiency, customer insights, and reduced costs, but may also replace some human jobs. The document then provides examples of how companies in various industries like telecom, manufacturing, financial services, and conservation are using AI capabilities like machine learning, natural language processing, forecasting and optimization to solve problems. In general, humans are good at common sense, creativity and empathy while machines are good at processing large datasets,
