2017 was an influential year for artificial intelligence (人工智能), not just in terms of the advancement of the technology itself, but also for the development of our understanding of AI's impact on our society.

    When we talk about AI, often we focus on the belief that it is going to take away certain types of jobs. However, we often ignore the fact that this technology will also slowly spread into most of our lives.

    Thanks to the development of AI, we are on the highway of IA, (human) intelligence augmentation (增强). Despite the great steps we've made in AI development and will continue to make in 2018, we are still years away from AI fully replacing human jobs. However, we are much closer to seeing the impact of AI spread into almost every job and the growth in human intelligence.

    Take a doctor for example: AI will soon be able to detect and diagnose common diseases more quickly and accurately than humans. Now, doctors can spend more of their time explaining the possible diagnoses, communicating with patients and developing unique, reliable treatment plans that are most effective for each specific patient.

    However, AI is so powerful and its adoption will only accelerate as it begins to help our work and allow us to focus on the parts of our job that are most important. But part of why AI is so attractive is also why it's so dangerous. That is, that same power allows AI that are making incorrect decisions to do so with greater speed and impact than humans have ever had.

    This is why, as AI becomes more useful in 2018, it will also become more closely examined. 2018 will be the year when companies purchasing AI products don't just ask about the power of AI—they will make sure that it is tested carefully in advance, minimizing their potential unexpected impact.

    A good teacher is many things to many people. In my own experience, the people I respect the most and think about the most are the teachers who demanded the most discipline (纪律) from their students.

    I miss one teacher in particular that I had in high school. I think she was a good teacher because she was a very strict person. I remember very clearly a sign on her classroom door. It was a simple sign that said,    "Laboratory: in this room the first five letters of the word was stressed not the last seven." In other words, labor for her was more important than oratory, which means making speeches.

    She prepared her work very carefully and told us to do the same. We got lots of homework from her. Once she had broken her arm, and everybody in the class thought that maybe the homework load would be reduced, but it continued just the same. She checked our work by stamping her name at the bottom of the papers to show that she had read them.

    I think sometimes teachers who demand the most are liked the least. But as time goes by, this discipline really seems to benefit the students.

Senses That Work Together

    When we think about how our senses work, we usually imagine them operating separately: you sniff a flower, and the smell is delivered uninterrupted from nose to brain. However, it's more complex than that. Most evidence for cross modal perception (知觉) comes from studies into sound and vision (视觉). But research that shows other senses crossing over is coming out all the time, and it seems that even sound and smell sometimes form an unlikely pairing.

    When New York researchers, Daniel Wesson and Donald Wilson, tried to find out the truth about a "mysterious” area of the brain called the olfactory tubercle, they had to deal with this fact. Originally, they only intended to measure how olfactory tubercle cells in mice responded to smell. But during testing, Wesson noticed that every time he put his coffee cup down, the mouse cells jumped in activity. In fact, the olfactory tubercle is well-placed to receive both smell and sound information from the outside world. Later they found that among separate cells, most responded to a smell but a significant number were also active when a sound was made. Some cells even behaved differently when smell and sound were presented together, by increasing or decreasing their activity.

    Of course, mice aren't people, so research team has been carrying out further experiments. They pulled together a group of people and gave them various drinks to smell. Participants were asked to sniff the drinks, and then match them to appropriate musical instruments and produce the notes at different levels. The results were interesting: piano was regularly paired with fruity fragrances; strong smells sounded like the instruments that are made of metal.

    Further research found that listening to different sounds can change your perceptions. Studying taste this time, the team ordered some special toffee (太妃糖) and put together “soundscapes” corresponding to bitterness and sweetness. Participants tasted similar pieces of toffee while listening to each soundscape, and found the toffee more bitter or sweeter, depending on which soundrack they were listening to.

    Studies like this are helping scientists correctly describe our understanding of the senses, and how the brain combines them with its advantage. The consequences are worth considering. Could we see musicians work together with chefs to produce sound-improved food and drink? Will you be ordering a coffee with a soundrack to bring out your favorite smell? Come to think of it, that could be one thing you hope coffee shop chains don't get round to.

Half a Day

    I walked alongside my father, holding his right hand. All my clothes were new: the black shoes, the green school uniform, and the red cap. They did not make me happy, however, as this was the day I was to be thrown into school for the first time.

    "Why school?" I asked my father. "What have I done?"

    "I'm not punishing you," he said, laughing. "School's not a punishment. It's a place that makes useful men out of boys. Don't you want to be useful like your brothers?"

    I was not convinced. I did not believe there was really any good to be had in tearing me away from my home and throwing me into the huge, high-walled building.

    When we arrived at the gate we could see the courtyard, vast and full of boys and girls. "Go in by you," said my father, "and join them. Put a smile on your face and be a good example to others."

    I hesitated and squeezed his hand firmly, but he gently pushed me from him. "Be a man", he said. "Today you truly begin life. You will find me waiting for you when it's time to leave."

    I took a few steps. Then the faces of the boys and girls came into view. I did not know a single one of them, and none of them knew me. I felt I was a stranger who had lost his way. But then some boys began to glance at me in curiosity, and one of them came over and asked, "Who brought you?"

    "My father," I whispered.

    "My father's dead," he said simply.

    I did not know what to say. The gate was now closed. Some of the children burst into tears. The bell rang. A lady came along and said, "This is your new home. There are mothers and fathers here, too. Everything that is enjoyable and beneficial is here. So dry your tears and face life joyfully."

    Well, it seemed that my misgivings had had no basis. From the first moments I made many friends. I had never imagined school would have this rich variety of experiences.

    Most Americans see their pets as family members, surveys show. Those with dogs are more likely to call themselves pet "parents" than pet "owners". There are more of these parents than ever. In big cities such as San Francisco and Seattle,(owned) dogs outnumber children.

    The ways in which companies are profiting from the trend are also becoming various. Kinds of dog food and various pet mattresses (垫子) are always in hot sale. And it is not surprising that, for pets, Americans spent more than $400 million only on Halloween costumes this year. Overall, annual spending on pet food and products in America has risen by around 40% over the past ten years.

    Now a pack of startups have sensed a fresh opportunity.

    Much as Airbnb has offered travelers another choice instead of staying in a hotel, two firms, Recover and DogVacay, want to give pet owners an alternative to kennels (养狗场) when away from home. The cost is around $30 a night, with the majority of that going to the sitter, who takes care of the dog, and around a fifth to the company﹣much less than you would spend to check your dog into a kennel.

    The other big sellingpoint is that pets will receive better treatment. There are ways, apparently, to vet (审查) dog hosts to the real pet lovers: only around 15% of those who apply to serve as sitters are passed. Besides offering more attention and room, Rover has launched a feature that helps customers to see how far their dog has been walked via the GPS in the host's phone. Like Airbnb, both DogVacay and Recover insure stays against accidents.

    Another advantage of the model is that consumers often use dog-sitting services many times a year, and they tend to be loyal. That has helped DogVacay and Recover attract a lot of money﹣around $140 million between them.

    But firms that connect pets with hosts will face great competition as they try to go global. Companies offering homestays for dog rapidly appear in many different countries, including Australia, Brazil and Britain. And unlike Airbnb, which pulls in customers thanks to its presence in lots of markets that people want to travel to, the network effect for services like DogVacay is local.

    Despite having predicted the trend early, such firms may never achieve the same scale as an Airbnb. But then no one ever said it was easy to be top dog.

    Finding a suitable name for a baby is a big deal in China. When picking out a Chinese name, parents usually select two or three characters that have a carefully thought out meaning, but when deciding on an English name, many of them struggle. That's where Jessup and her company, Special Name, come in. In the last few years, Jessup has helped name 677,900 Chinese babies, and earned over $400,000 in the process, more than enough to pay her college fees.

    Jessup came up with the idea for Special Name in 2015, after accompanying her father on a business trip to China. One of her dad's business partners, a Mrs. Wang, asked her to help choose an English name for her daughter. Jessup felt honored and quickly realized the importance of choosing a proper name in Chinese culture. The woman wanted people to be surprised by the things her daughter could achieve, so Jessup suggested the name "Eliza" after the character Eliza Doolittle from the play Pygmalion. Mrs. Wang seemed delighted with Jessup's choice. "If Mrs. Wang needed this service, maybe other parents would as well," Jessup thought.

    After returning to UK, Jessup borrowed ￡1,500 from her parents and paid a web designer to build a website, She then spent her free time filling up a database(数据库)with around 4,000 English names, associating them with five major personality characteristics, like honesty and optimism.

    In the beginning, Jessup offered the service for free to promote the website, but later, she started charging fees. The business is almost completely self-sufficient, requiring only a small team in China that manages technical operations. She updates the database each month, allowing her to focus full-time on studies.
