___225___（satisfy）that you haven’t missed any important messages, you log onto Facebook. You check to see whether your friends posted any updates while you were sleeping.
Then it’s off to Tik Tok. You follow hundreds of friends, acquaintances, and celebrities. Surely someone has posted something worthy___226___（read）. Unfortunately, they haven’t.
With nothing of interest___227___（happen）on social media, you visit your favorite news media sites to find out what’s going on the world. After all, you don’t want to miss the day’s major headlines.

A SPECTRE is haunting workers—the rise of artificial intelligence (AI)
The fear is that smart computer programs will eliminate millions of jobs, condemning a generation to minimum-wage drudgery or ___235___ (enforce) idleness. Never mind the robots, fear the software. There is no need to be so gloomy, say Ken Goldberg of the University of California, Berkeley, and Vinod Kumar, the chief executive of Tata Communications, a unit of India’s biggest business house (which stands ___236___ (profit) from the spread of AI). They have produced a report that is much more optimistic about the outlook for ordinary employees. In many cases, it says, job satisfaction will be enhanced by the elimination of mundane tasks, giving people time to be ___237___ (creative). Their views are backed up by a survey of 120 senior executives, conducted for the report, which found that more of them (77%) thought that AI would create new roles than believed ___238___ would replace existing positions (57%; respondents could choose both options). Extra skills ___239___ be needed to cope with the new technology and more than half of the bosses are already taking steps to train their workforces. No previous technology shifts ___240___ (have) as negative effects on employment as was first feared. The authors note some well-known examples. Bar-code scanners did not eliminate the role of cashiers in America; jobs in the retail industry grew at an annual rate of more than 2% between 1980 and 2013. The arrival of automated teller machines (ATMS) spared bank employees the job of delivering cash and freed them to offer financial advice ___241___ customers. Some jobs could be made a lot easier by AI. One example is lorry-driving. Such is the fear ___242___truck drivers will be replaced by autonomous vehicles. But maneuvering a lorry around busy streets is far harder than driving down the motorway. So the driver could switch into automatic mode (and get some rest) when outside the big cities, and take over the wheel once again when ___243___ (near) the destination. The obvious analogy (类比) is with jetliners, ____244____ the pilots handle take-off and landing but turn on the computer to cruise at 35,000 feet. Using AI may prevent tired drivers from causing accidents.

We may simply end up adding new devices to our screen-added lives, _____254_____ it could change everything again. As I argued, in many ways screens have become too dominant in our lives. The sooner we find something else, the better.
