The contemporary artificial intelligence systems inspired by neurons and nervous system is known for its capability of listening and seeing. The vast computational ability and data mining potential make them great in beating chess grandmasters and winning million-dollar quiz shows but they have trouble with functions involving a great deal of imagination and individuality like composing music or writing stories. This creates a hurdle in relating to the world as it is. Now researchers are on the verge of endowing them with the capability of olfaction, which will take them one step closer to overcoming constraints of reasoning meaningfully in the world. Unlike animals and even some plants, the human olfactory system is not sensitive enough to capture the information transmitted through the air in the form of smell.
