This year, we also explored many ways AI and machine learning are now being used. For example, some U.S. judges use machine learning systems to help them decide when, and for how long, criminals should be jailed. The system uses computers to examine data from thousands of court cases.

One fast-growing area of AI is facial recognition, which is increasingly being used for security purposes. Recently, Hartsfield-Jackson Atlanta International Airport became the first in the U.S. to permit passengers to use facial recognition technology to get on flights. A Chinese company showed an AI system it developed to recognize individuals by body shapes and walking movements. The system has already been used by Chinese police in Beijing and Shanghai.

In addition, machine learning was used during 2018 to predict results of the World Cup Soccer Games. The technology also created artwork that sold for a large amount of money. And it is being used to help farmers save time and money, while reducing environment-harming chemicals. Other technology systems are being used to follow farm animals and wildlife to collect information on their activities.
