This paper tackles the concept of AI, its justification, and its applications in the field of education in general, and in the field of teaching/learning English Language, in particular. The paper focuses specifically on the incorporation of artificial intelligence (AI), which includes a wide range of technologies and methods, such as machine learning, adaptive learning, natural language processing, data mining, crowdsourcing, neural networks or an algorithm, into foreign language learning and teaching. First, the paper is concerned with changes brought to education in general and foreign language education specifically through the application of AI-powered tools and discusses ICALL (intelligent computer assisted language learning) as a subset of CALL. Second, it delineates the implementation of AI in the field of ESL/EFL. Third, it summarizes the consequences of applying AI-powered tools for foreign language education. Fourth, it discusses the benefits and challenges that the AI implementation entails. Finally, it puts forward a number of guidelines and recommendations for education policy-makers targeting the basic requirements for AI implementation.
