Artificial intelligence is the capability of a machine to imitate intelligent human behavior.
Early AI is pattern matching; it enables machines to imitate intelligent behavior, but it cannot be equated with human intelligence.
Pattern matching is often enhanced with AI planning that streamlines the pattern-matching process.
Strong AI imbues machines with human qualities, including self-awareness and emotions, whereas weak AI enables machines to perform specific tasks.
Strong AI remains relegated to the realm of science fiction.
