What is Artificial Narrow Intelligence and Artificial General Intelligence

At the heart of artificial intelligence is the idea that one day we'll be able to build a machine that's as smart as a human. That type of AI is called Artificial General Intelligence or AGI. The most prominent AI experts today think (including DeepMind CEO Demis Hassabis, Google AI Chief Jeff Dean, and Stanford AI director Fei-Fei Li) this would take quite a few years before it is built. The years ranged from 2029 to 2200, with the average estimate being 2099 -- 81 years from now.
