AI can be spitted into narrow AI and AGI. Narrow AI is easier to grasp because it has to do with building micromouse robots, in game AI, pick&place robots and chatbots.
The interesting situation is, that the subject of AI is large domain within science. Around 5 Million papers and endless amount of books were written about the subject. So the question is not what is AI itself, but the question what was published about the subject.
