Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, testing or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers (低头族).

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident site and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

    Although the ending sounds overstated, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “The neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    Every week in China, millions of people will sit in front of their TVs watching teenagers compete for the title Character Hero, which is a Chinese-style spelling bee (拼写大赛). In this challenge, young competitors must write Chinese characters by hand. To prepare for the competition, the competitors usually spend months studying dictionaries.

    Perhaps the show's popularity should not be a surprise. Along with gunpowder and paper, many Chinese people consider the creation of Chinese calligraphy (书法) to be one of their primary contributions to civilization. Unfortunately, all over the country, Chinese people are forgetting how to write their own language without computerized help. Software on smart phones and computers allows users to type in the basic sound of the word using the Latin alphabet. The correct character is chosen from a list. The result? It's possible to recognize characters without remembering how to write them.

    But there's still hope for the paint brush. China's Education Ministry wants children to spend more time learning how to write.

    In one Beijing primary school we visited, students practice calligraphy every day inside a specially decorated classroom with traditional Chinese paintings hanging on the walls. Soft music plays as a group of six-year-olds dip brush pens into black ink. They look up at the blackboard often to study their teacher's examples before carefully attempting to reproduce those characters on thin rice paper. “If adults can survive without using handwriting, why bother to teach it now?” we ask the calligraphy teacher, Shen Bin, “The ability to write characters is part of Chinese tradition and culture,” she reasons. “Students must learn now so they don't forget when they grow up.” says the teacher.

    People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking. They try to find a solution by trial and error. However, when all these methods fail, the person with a problem has to start analyzing. There are six stages in analyzing a problem.

    First the person must recognize that there is a problem. For example, Sam's bicycle is broken, and he cannot read it to class as he usually does. Sam must see that there is a problem with his bicycle.

    Next the thinker must define the problem. Before Sam can repair his bicycle, he must find the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific.

    Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully.

    After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels.

    Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels.

    Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. In short, he has solved the problem.

    Karen Bystedt was born in Israel, but lived in London and California as a child. In 1982, as a photography (摄影) student at New York University, she was photographing male models for a book when she came across an ad featuring Andy Warhol, a very famous artist. She thought it would be really great to put him in her book.

    So she called Andy Warhol at his studio in Union Square and asked if she could photograph him.

Two weeks later, Bystedt took a rented Hasselblad camera and lights to Warhol's famed "Factory" on 14th street. She ended up taking 36 pictures, and published two in her book, Not Just Another Pretty Face, published in 1983. Warhol came to its launch (发行) party—and that was the last time she saw him.

    A few years later, she packed the portraits in a box and moved to Los Angeles. But after she'd gotten settled, she couldn't find them. She couldn't remember whether she had given the photos away or just left them in some forgotten storage unit. Either way, she thought they were lost forever.

    In 2011, Bystedt became determined to find the missing films(底片). She spent two weeks going through two old garages, where she had put a bunch of belongings decades before. In a cardboard box, she found ten of the original films, covered in dust. She and a friend spent four months digitizing and cleaning the images up, pixel(像素) by pixel.

    Bystedt was not content to merely publish the unseen photos. She invited contemporary artists to paint over and around her Warhol pictures, breathing new life into her old work. So she began reaching out to artists, seeing if they would be interested in putting their own stamp on the pictures.

    The responses was overwhelming. Bystedt's new exhibit, "The Lost Warhols," opened on May 1, 2018 at 178 Sixth Avenue in Soho, New York, included 66 different interpretations of her portraits from 34 artists.

Ammaar Reshi, 28, has been fascinated by technology since he was a child. One day, when he was experimenting with an AI-powered chatbot, he began to consider how artificial intelligence could be used to create a basic children's book to give to his friends. Without ever picking up a pen and paper, he created a 12-page picture book. 

Just 72 hours later, Reshi self-published his book on Amazon's digital bookstore. The next day he got the paperback（平装书）, which was made available for free through another Amazon service called KPD. 

Reshi said he paid nothing to have the book created and published, although he has already paid for a $30-per-month Midway subscription. Impressed by the speed and results of his project, Reshi shared the experience in a Twitter thread that attracted more than 2,000 comments and 5,800 retweets（转发）. 

Reshi stated that he received great feedback（反馈）from users, who lauded his creative work at first. But the next day, the replies were negative. "There was this incredibly passionate reaction," Reshi said. "At 4 am, I was woken up by my phone ex ploding every two minutes with a new tweet saying things like ‘We hate you'. "

Reshi was taken aback by the outpouring of emotion in response to what was supposed to be a present for some friends' children. He didn't realize he had landed in the heart of a much broader argument. 

Some artists have expressed concern that AI art generators are stealing their work in response to Reshi's book. And some artists claim that their work has been used without their permission to train Al picture generators. 

"I wouldn't even call myself an author," Reshi said. "The AI is essentially the ghostwriter（代笔者）, and the other AI is the illustrator. " But he thought the process was creative.
