weak artificial intelligence (ANI): weak artificial intelligence is artificial intelligence that is good at dealing with a single aspect. For example, Alfago can only play chess, and Apple Siri can only be your voice assistant at present. Tesla's driverless system also contains countless weak artificial intelligence. Don't deny that we have entered the world of artificial intelligence, but the level is still relatively low. Even weak artificial intelligence belongs to a relatively low stage

strong artificial intelligence (AGI): human-level artificial intelligence. Strong artificial intelligence refers to artificial intelligence that can compete with human beings in all aspects, and it can do all the brain work that human beings can do. Creating strong artificial intelligence is much more difficult than creating weak artificial intelligence, and we can't do it yet. Professor Linda Gottfredson defines intelligence as "a broad psychological ability, which can think, plan, solve problems, think abstractly, understand complex ideas, learn quickly and learn from experience." Strong artificial intelligence should be as handy as human beings in these operations.

super artificial intelligence (ASI): Nick Bostrom, an Oxford philosopher and well-known artificial intelligence thinker, defines super intelligence as "much smarter than the smartest human brain in almost all fields, including scientific innovation, general knowledge and social skills." At present, the development of AI is undoubtedly in the stage of weak artificial intelligence development. However, in the weak artificial intelligence stage, the development of AI should also be divided into three stages: technology-driven stage, data-driven stage and scene-driven stage. We are now in the early stage of weak artificial intelligence-the technology-driven stage.
