In the movies and on television, artificial intelligence is typically depicted as something sinister that will upend our way of life. When it comes to AI in business, we often hear about it in relation to automation and the impending loss of jobs, but in what ways is AI changing companies and the larger economy that don’t involve doom-and-gloom mass unemployment predictions?

A recent survey of manufacturing and service industries from Tata Consultancy Services found that companies currently use AI more often in computer-to-computer activities than in automating human activities. One common application? Preventing electronic security breaches, which, rather than eliminating IT jobs, actually makes those personnel more valuable to employers, because they help firms prevent hacking attempts.

Here are a few other ways AI is aiding companies without replacing employees:

Better hiring practices 

Companies are using artificial intelligence to remove some of the unconscious bias from hiring decisions. “There are experiments that show that, naturally, the results of interviews are much more biased than what AI does,” says Pédro Domingos, author of The Master Algorithm: How the Quest for the Ultimate Learning Machine Will Remake Our World and a computer science   41      One company that’s doing this is called Blendoor. It uses analytics to help identify where there may be bias in the hiring process.

More effective marketing

Some AI software can analyze and optimize marketing email subject lines to increase open rates. One company in the UK, Phrasee, claims their software can outperform humans by up to 10 percent when it comes to email open  rates. This can mean  millions more  in revenue.      42      These are “tools that help people use data, not a replacement for people,”says Patrick H. Winston, a professor of artificial intelligence and computer science at MIT.

Saving customers money

Energy companies can use AI to help customers reduce their electricity bills, saving them money while helping the environment. Companies can also optimize their own energy use and cut down on the cost of electricity. Insurance companies, meanwhile, can base their premiums on AI models that more accurately access risk. “Before, they might not insure the ones who felt like a high risk or charge them too much,” says Domingos,      43      

Improved accuracy

“Machine learning often provides a more reliable form of statistics, which makes data more valuable,” says Winston. It “helps people make smarter decisions.”     44    

Protecting and maintaining infrastructure

A number of companies, particularly in energy and transportation, use AI image processing technology to inspect infrastructure and prevent equipment failure or leaks before they happen. “If they fail first and then you fix them, it’s very expensive,” says Domingos.      45     

[A]I replaces the boring parts of your job. If you’re doing research, you can have AI go out and look for relevant sources and information that otherwise you just wouldn’t have time for.

[B]One accounting firm, EY, uses an AI system that helps review contracts during an audit. This process, along with employees reviewing the contracts, is faster and more accurate.

[C]There are also companies like Acquisio, which analyzes advertising performance across multiple channels like Adwords, Bing and social media and makes adjustments or suggestions about where advertising funds will yield best results.

[D]You want to predict if something needs attention now and point to where it’s useful for employees to go to.

[E]Before, they might not insure the ones who felt like a high risk or charge them too much, or they would charge them too little and then it would cost [the company] money.

[F]We’re also giving our customers better channels versus picking up the phone to accomplish something beyond human scale.

[G]AI looks at résumés in greater numbers than humans would be able to, and selects the more promising candidates.

Part C

Directions:

Read the following text carefully and then translate the underlined segments into Chinese. Write your answers on the ANSWER SHEET. (10 points)

World War Ⅱ was the watershed event for higher education in modern Western societies. (46)Those societies came out of the war with levels of enrollment that had been roughly constant at 3-5% of the relevant age groups during the decades before the war. But after the war.great social and political changes arising out of the successful war against Fascism created a growing demand in European and American economies for increasing numbers of graduates with more than a secondary school education. (47) And the demand that rose in those societies for entry to higher education extended to groups and social classes that had not thought of attending a university before the war. These demands resulted in a very rapid expansion of the systems of higher education, beginning in the 1960s and developing very rapidly (though unevenly) during the 1970s and 1980s. The growth of higher education manifests itself in at least three quite different ways, and these in turn have given rise to different sets of problems. There was first the rate of growth: (48) in many counties of Western Europe, the numbers of students in higher education doubled within five-year periods during the 1960s and doubled again in seven, eight, or 10 years by the middle of the 1970s.

Second, growth obviously affected the absolute size both of systems and individual institutions. And third, growth was reflected in changes in the proportion of the relevant age group enrolled in institutions of higher education.

Each of these manifestations of growth carried its own peculiar problems in its wake. For example, a high growth rate placed great strains on the existing structures of governance, of administration, and above all of socialization. When a faculty or department grows from, say, five to 20 members within three or four years, (49) and when the new staff predominantly young men and women fresh from postgraduate study, they largely define the norms of academic life in that faculty. And if the postgraduate student population also grows rapidly and there is loss of a close apprenticeship relationship between faculty members and students, the student culture becomes the chief socializing force for new postgraduate students, with consequences for the intellectual and academic life of the institution—this was seen in America as well as in France, Italy, West Germany, and Japan. (50)High growth rates increased the chances for academic innovation; they also weakened the forms and processes by which teachers and students are admitted into a community of scholars during periods of stability or slow growth. In the 1960s and 1970s, European universities saw marked changes in their governance arrangements, with empowerment of junior faculty and to some degree of students as well.
