Turning on the TV, a wonderful scene comes to your eyes — a group of men, tall, strong and handsome, and women, young, beautiful and attractive, too. Together they eat in the finest restaurants, traveling everywhere around the world by luxurious planes and pleasure ships. They are models.

Do you envy them？What sort of life are models leading？Is it a wonderful life for a young lady or a young man?

A few models are well-known actors or actresses who can make a lot of money only by showing themselves off in commercials. But the majority of them are just curious to see what it is like. They^’d like to be models just because they are attracted by what they imagine — models earn a lot of money and lead a glorious life. This is true for those who are very successful. However, most models find it difficult to get work. Very few can earn enough to live on, and for all models their expenses are high. Their agents claim about 20% of the earnings, and no model will get very far without a clever agent. Besides, they have to buy good clothing. They also have to pay to travel to interviews and reach the places where the work is to be done.

Interviews for a model job are known as cattle markets in the modeling world, and not without a good reason. A top model can choose his or her work, demand and receive high fees and has his or her expenses paid. But for most models, the situation is quite different. An agent or employer inspects each model much as a farmer inspects cattle at a market. Intelligence, qualifications and personal characteristics count for little against good looks and tight figures. For all except the very few lucky ones, the life of a model is a continual search for work, trying to sell him or her in the face of fierce competition and, sometimes, not particularly moral standards on the part of some employers.

Immigration officials at the airport look suspiciously at a girl whose passport shows her occupation as “Model”, and these are men and women of considerable experience of the world. It comes no surprise to find that some models prefer to put “Secretary” or “Businessman” as their jobs in their passports.

People worry that developments in Artificial Intelligence, or A.I., will bring about a point in history when A. I. overtakes human intelligence, leading to an unimaginable revolution in human affairs. Or they wonder whether instead of our controlling artificial intelligence, it will control us.

The situation may not arise for hundreds of years to come, but this doesn’t mean we have nothing to worry about. On the contrary, The A. I. products that now exist are improving faster than most people realize and promise to fundamentally transform our world, not always for the better. They are only tools, not a competing form of intelligence. But they will reshape what work means and how wealth is created.

Unlike the Industrial Revolution and the Computer Revolution, the A. I. revolution is not taking certain jobs and replacing them with other jobs. Instead, it is believed to cause a wide - scale elimination of jobs -- mostly lower - paying jobs, but some higher - paying ones, too.

This transformation will result in enormous profits for the companies that develop A.I., as well as for the companies that adopt it. We are thus facing two developments that do not sit easily together; enormous wealth concentrated in relatively few hands and enormous numbers of people out of work. What is to be done?

Part of the answer will involve educating or retraining people in tasks A.I. tools aren’t good at. Artificial intelligence is poorly suited for jobs involving creativity, planning and “cross - field” thinking. But these skills are typically required by high - paying jobs that may be hard to retrain displaced workers to do. More promising are lower - paying jobs involving the “people skills” that A.I. lacks: social workers, barmen, doormen -- professions requiring human interaction. But how many barmen does a society really need?

The solution to the problem of mass unemployment will involve “service jobs of love.” These are jobs that A. I. cannot do, that society needs and that give people a sense of purpose. Examples include accompanying an older person to visit a doctor, helping at an orphanage and serving as a sponsor at charity organization. The volunteer service jobs of today, in other words, may turn into the real jobs of the future.

Other volunteer jobs may be higher - paying and professional, such as compassionate medial service providers. In all cases, people will be able to choose to work fewer hours than they do now.

Many managers believe that overworking is an evidence of devotion from their employees’ side. Still few others regard this custom as a threat to the workers’ work-life balance, which may negatively influence the level of productivity and efficiency.

Employees at Amsterdam design studio Heldergroen won’t be putting in much overtime. Not in the office, at any rate. That’s because every day at 6:00 pm, their desks, tables and other work surfaces, with their computers attached, are lifted to the ceiling by steel cables （绳索）normally used to move heavy props（道具）in theatrical productions. If you leave a half-eaten sandwich on your desk, you’re out of luck.

“Once the chairs and other workplace paraphernalia are cleared away, the space is free for evening and weekend use as a dance floor, yoga studio ... or anything else you can think of – the floor is actually yours, ” doctor Sander Veenendaal said.

In a way, the office space itself is working overtime for Heldergroen, bringing about lots of publicity and carrying an enlightened（有启发的）message of career-life balance far and wide.”We think that doing activities like this makes it easier for people to work here,” says Veenendaal. “You know when it is time to relax or do something else that inspires you.”

That sounds awesome. There’s just one catch. In the morning, the desks reappear and everybody has to go back to work.
