The U.S. government has no official definition of artificial intelligence, or AI. According to the Congressional Research Service, AI refers to a computer system capable of human-level cognition using one of two categories, narrow AI and general AI. Narrow AI systems “can perform only the specific task that they were trained to perform, while general AI systems—which does not yet, and may never, exists—would be capable of performing a broad range of tasks, including those for which they were not specifically trained.”
