Final answer:
The current state of the art of AI is Narrow AI, which focuses on specialized tasks and is embodied in technologies like Siri or social media bots. Option B is correct.
Step-by-step explanation:
The generally agreed upon current state of the art of AI is B. Narrow AI. This term denotes a type of artificial intelligence that is designed to perform a single task or a limited range of tasks, unlike Strong AI, which aims to perform multiple cognitive functions similar to a human.
Current instances of Narrow AI include technologies like Apple's Siri or social media bots. These systems are specialized in particular domains and do not possess the capabilities of human-like consciousness or reasoning across a broad spectrum of activities. Nevertheless, the future potential of AI is vast, with advancements occurring regularly, leading towards more complex systems.
There are four general types of artificial intelligence, which include reactive machines, limited memory, theory of mind, and self-aware systems. Presently, AI is largely operating at the reactive machines and limited memory stages, with self-driving cars and quantum computers being leading examples of industries where AI is already prevalent.
Moreover, the field of AI stirs up significant ethical and governance debates due to the myriad social implications that accompany the technology's advancement, such as privacy concerns, cybercrime, and the impact on job markets.
Strong AI, which performs multiple cognitive tasks like humans, is not yet a reality. AI systems range from reactive machines to limited memory, and advancements continue to shape various industries and ethical discussions.
