Does Fame Drive You Crazy?

    As self — driving cars come closer to being common on American roads, much of the rhetoric (说辞) promoting them has to do with safety. About 40,000 people die on U. S. roads every year, and driver errors are linked to more than 90 percent of crashes. But many of the biggest advocates of autonomous vehicles aren't car companies looking to improve the safety of their existing products. Huge backing for self - driving technologies is coming from Silicon Valley giants like Google and Apple.

    Those of us who have studied the relationship between technology and society tend to look more carefully at the motivations behind any technological push. In this case, it's clear that in addition to addressing safety concerns, Silicon Valley firms have a strong incentive (动机) to create a new venue for increasing the use of their digital devices. Every minute people spend on their mobile phones provides data - and often money - to tech companies.

    At present, digital devices and driving are in conflict: There are serious, often fatal, consequences when drivers use smartphones to talk or to text. Regulators and safety advocates look to resolve dial conflict by banning phone use while driving - as has happened in virtually every state. But the tech companies are taking a different approach. The obvious answer for Silicon Valley is creating an antomobile in which continuous cellphone use no longer poses a threat to anyone.

    In recent years, the amount of time adults spend on their mobile devices has grown rapidly. At the moment, it's around four hours a day for the average adult in the U. S. However, that rapid growth is likely to slow down as people run out of time that ' s available for them to use their devices. Unless, of course, there's a new block of time that suddenly opens up. The average American now spends about 48 minutes in a car every day, a sizable opportunity for increased cellphone use.

    So as the public conversation around autonomous cars highlights the safety advantages, don't forget the tech industry ' s powerful desire for more profits, which goes well beyond simply saving us from ourselves.

A few months after we moved to a small city in France, I wanted to meet my husband for lunch at the university where he worked. I got lost. I had to call him for help. One of his friends said to him later, "How could she get lost? She just needed to go straight."

Well, no. That's the problem. You never "just go straight", because France is the land of roundabouts (弯道). Highways, major streets, little village lanes – if you go straight long enough, you'll end up going in circles.

    Even after a year here, I'd still get lost going to the grocery store, or just about anywhere that wasn't within a hundred yards of my house.

I admit I have a horrible sense of direction, can't read a map, and am not such a good driver. Plus, I've been spoiled (宠坏) by living in American cities, where you just indeed need to "go straight". But in France, driving became my nightmare — the roads are roundabouts within roundabouts.

    Finally I found a solution: a GPS program on my smart phone. I rely on it to get anywhere, even places I've been.

    But it does leave me feeling very bad and helpless when, often, the program doesn't work, can't find a GPS signal, or gives wrong information. I'd have to wait until my GPS gets recovered, or else I use my old solution: I call my husband. Is the GPS making us more stupid, or helping us going around more? In my case, it's probably both.

    At times my mom has been uncomfortable seeing some quality in me. For example, when I was 12, I went to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about it. She kept telling me how things were different in Puerto Rico, to always put on sunscreen, not to wander away from my grandmother, and other warnings. She helped me pack and did not leave the airport until she saw my plane take off.

    But despite her worries, she let me go on my own. As I moved into my teens, she continued to give me space to grow and learn, even when it might have been difficult for her. When I reached my senior year, I decided to move away for college. Once again I found that I differed from my peers: while many of them wanted to stay close to home, I couldn't wait to be out in the world on my own. While my mom may not have been happy at the thought of my going away, she was supportive and excited for me.

    One big thing I realized during my senior year, as my mom granted me more freedom, was that she actually believes in me and trusts me. That means a lot. Most of my life, and especially when I was little, the main person I tried to impress in my schoolwork or other things was my mother. I knew she expected nothing but the best from me. Sometimes it was hard to live up to her standards: getting a single B on my report card would make me feel bad because I knew she wanted me to have all A's.

    I know that her high standards have helped me stay focused on what's important, like education, and made me who I am. I am thankful for her support and involvement in my life. Most of all I respect her. She is the strongest woman I know and that's why I have turned out so strong and independent.

    Whenever something looks interesting or beautiful, there's a natural impulse(冲动) to want to own and preserve it — which means, in this day and age, that we're likely to reach for our phones to take a picture.

    Though this would seem to be an ideal solution, there are two big problems associated with taking pictures. Firstly, we're likely to be so busy taking the pictures that we forget to look at the world whose beauty and interest drove us to take a photograph in the first place. And secondly, because we feel the pictures are safely stored on our phones, we never get around to looking at them, so sure are we that we'll get around to it one day.

    These problems were noticed right at the beginning of the history of photography, when the average camera was the size of a grandfather clock. The first person to notice them was the English art critic, John Ruskin. He was a traveler who realized that most tourists make a boring job of noticing or remembering the beautiful things they see. He argued that humans have a natural tendency to respond to beauty and wish to have it, but that there are better and worse expressions of this desire. At worst, we get into buying souvenirs or taking photographs. But, in Ruskin's eyes, there's one thing we should do and that is attempt to draw the interesting things we see, no matter whether we have any talent for doing so.

    Ruskin was very upset by how seldom people notice details. He strongly disliked the travelers who prided themselves on covering Europe in a week by train. "If he be truly a man, no harm to go slow; for his glory is not at all in going, but in being."

    Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer?

    This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes—clothes that have minds of their own! Scientists, working for the company, have invented a kind of cloth that can be mixed with flexible (有弹性的) electronic materials to create intelligent clothing. The results are electronic garments (衣服).

    If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will produce electricity by using body heat. These clothes are 100 percent shock proof, they say.

    The Electrotextiles team has also created the world's first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These 'lap-tap' gadgets (器具), are all set to take over laptop computers!

    Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim (牛仔布) jacket with flexible earphones sewn into the hood and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.

    Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?
