Artificial intelligence has progressed more slowly than originally expected, as tasks requiring high-level reasoning and human-level intelligence have proved much more difficult than initially thought. While early researchers believed that human-level AI was close at hand, progress has been gradual and challenges remain in developing general artificial intelligence that can match human abilities. Recent advances have focused on narrow applications rather than general human-level intelligence.
