• 21．Technology is forever changing the way we get our news.Most people now get a lot of their news on electronic devices，instead of traditional media，such as newspapers，television or radio.An increasing number of people also report turning to social media for information.
     Now，there is a new technology that could greatly change the way we get the news：computer-created news readers.China has launched what it called the world's first artificial intelligence，or AI news presenters.
     The news readers，supported by machine learning technology，are based on two real-life Chinese newsmen.One is able to present news broadcast in English；the other，in Mandarin Chinese.A report said machine learning was used to examine video images and sounds of the two newsmen.Similar technology has been used to create video products known as "deepfake videos".A deepfake video is a video that looks real，but was electronically changed.Such videos can make people appear to say things they never said.
     It's said that the AI presenters will be a great improvement to the news team because they "can work 24 hours a day" on its website and on social media.One of the presenters even promised to "work tirelessly" to keep people informed.Some machine learning experts said the system showed off China's latest progress in voice recognition，text-to-speech technology and data analysis.
     Others wondered about the effects robots might have on employment and workers.Some people argued that only low-level jobs requiring heavy labour will be easily replaced by robots.Others praised the technology as a way for companies to make money from low-cost labour machines.
     Anyway，for its great potential，some businesses have experimented with similar technology for possible use in news operations.
