Write short notes on Strong AI.

Strong AI is also known as "General AI", "Human-Level AI" or "Artificial General Intelligence (AGI)". It refers to those Artificial Intelligence (AI) systems that can exhibit human-level intelligence across a variety of tasks and domains. These hypothetical systems can be capable of comprehending, learning and applying knowledge in a similar capacity as humans do. Strong AI is still a work in progress and not yet a reality. Because it does not actually exist yet, the only true examples of AGI are found in works of science fiction like Star Trek: The Next Generation, Wall-E and Her.
