AI refers to artificial intelligence - the ability of machines to exhibit intelligent behavior such as reasoning, planning, learning, etc.  AI research is a very exciting field, with tremendous potential to improve our lives in many ways, as smart computer systems can automate various complex tasks and serve as intelligent helpers and assistants.  However many people are also somewhat concerned about the potential dangers and ethical issues associated with highly advanced AI systems.  Overall the future of AI is quite uncertain, but it is definitely an exciting and important field to follow.

AI is the field of study concerned with developing computer systems that exhibit intelligent behavior.  Intelligence can be broadly defined as the ability to perceive and interact with the environment, perform complex mental tasks, and adapt to new situations.  Artificial intelligence aims to develop computer systems that can exhibit intelligent behavior similar to humans.  Different approaches to AI focus on different aspects of intelligence, and employ a variety of techniques and technologies developed in other fields, including machine learning, neural networks, genetic algorithms, techniques from statistical psychology, decision theory, etc.  Many of these related fields of research are also regarded as subfields of AI.
