Last night I was driving from Harrisburg to Lewisburg, a distance of about eighty miles. It was late. Several times I got stuck behind a slow-moving truck on a narrow road with a solid white line on my left, and I became increasingly impatient.
At one point along an open road, I came to a crossing with a traffic light. I was alone on the road by now, but as I drove near the light, it turned red and I made a stop. I looked left, right and behind me. Nothing. Not a car, no suggestion of car lamps, but there I sat, waiting for the light to change, the only human being for at least a mile in any direction.
I started wondering why I refused to run the light. I was not afraid of being caught, because there was clearly no policeman around, and there certainly would have been no danger in going through it.
Much later that night, the question of why I'd stopped for that light came back to me. I think I stopped because it's part of a contract(契约) we all have with each other. It's not only the law, but it's an agreement we have, and we trust each other to honor it: we don't go through red lights.
Trust is our first inclination(倾向). Doubting others does not seem to be natural to us. The whole construction of our society depends on mutual(相互)trust, not distrust. We do what we say we'll do;we show up when we say we'll show up; and we pay when we say we'll pay. We trust each other in these matters, and we're angry or disappointed with the person or organization that breaks the trust we have in them.
I was so proud of myself for stopping for the red light that night.

What was the author's immediate action when the traffic light turned red?

Hollywood's theory that machines with evil(邪恶) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics(控制论), put it this way "If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose which we really desire."

A machine with a specific purpose has another quality, one that we usually associate with living things a wish to preserve its own existence. For the machine, this quality is not in-born, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard.

The possibility of entering into and losing such a match should concentrating the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.

Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams-yet that is not possible unless machines share the goals of humans. Others say we can just "switch them off" as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, "Anyone who expects a source of power in the transformation of these atoms is talking moonshine." However, on September 12, 1933, physicist Leo Szilard invented the neutron-induced(中子诱导) nuclear chain reaction.

Measles(麻疹), which once killed 450 children each year and disabled even more, was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine(疫苗). But the disease is making a comeback, caused by a growing anti-vaccine movement and misinformation that is spreading quickly. Already this year, 115 measles cases have been reported in the USA, compared with 189 for all of last year.

The numbers might sound small, but they are the leading edge of a dangerous trend. When vaccination rates are very high, as they still are in the nation as a whole, everyone is protected. This is called "herd immunity", which protects the people who get hurt easily, including those who can't be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn't work.

But herd immunity works only when nearly the whole herd joins in. When some refuse vaccination and seek a free ride, immunity breaks down and everyone is in even bigger danger.

That's exactly what is happening in small neighborhoods around the country from Orange County, California, where 22 measles cases were reported this month, to Brooklyn, N.Y., where a 17-year-old caused an outbreak last year.

The resistance to vaccine has continued for decades, and it is driven by a real but very small risk. Those who refuse to take that risk selfishly make others suffer.

Making things worse are state laws that make it too easy to opt out(决定不参加) of what are supposed to be required vaccines for all children entering kindergarten. Seventeen states allow parents to get an exemption(豁免), sometimes just by signing a paper saying they personally object to a vaccine.

Now, several states are moving to tighten laws by adding new regulations for opting out. But no one does enough to limit exemptions.

Parents ought to be able to opt out only for limited medical or religious reasons. But personal opinions? Not good enough. Everyone enjoys the life-saving benefits vaccines provide, but they'll exist only as long as everyone shares in the risks.

It was a cold March day in High Point, North Carolina. The girls on the Wesleyan Academy softball were waiting for their next turns at bat during practice, stamping their feet to stay warm, Eighth-grader Taylor Bisbee shivered(发抖) a little as she watched her teammate Paris White play. The two didn't know each other well -Taylor had just moved to town a month or so before.

Suddenly, Paris fell to the ground,"Paris's eye rolled back," Taylor says. "She started shaking . I knew it was an emergency."

It certainly was, Paris had suffered a sudden heart failure. Without immediate medical care, Paris would die. "Does anyone know CPR?"

CPR is a life-saving technique. To do CPR, you press on the sick person's chest so that blood moves through the body and takes oxygen to organs. Without oxygen the brain is damaging quickly.

Amazingly, Taylor had just taken a CPR course the day before. Still, she hesitated. She didn't think she knew it well enough. But when no one else came forward, Taylor ran to Paris and began doing CPR, "It was scary. I knew it was the difference between life and death," says Taylor.

Taylor's swift action helped her teammates calm down. One girl called 911. Two more ran to get the school nurse, who brought a defibrillator, an electronic devices(器械) that can shock the heart back into work. Luck stayed with them Paris' heartbeat returned.

"I know I was really lucky," Paris say now. "Most people don't survive this. My team saved my life"

Experts say Paris is right For a sudden heart failure, the single best chance for survival is having someone nearby step in and do CPR quickly.

Today, Paris is back on the softball team. Taylor will apply to college soon. She wants to be a nurse. "I feel more confident in my actions now," Taylor says."I know I can act under pressure in a scary situation."

I'm a 34-year-old man, married, lived in a nice house, and have a successful career as an educational consultant. But my life was not always so great. I had a learning disability from an early age. I went to a special school where I got plenty of extra help. Still, I suffered the rest of my school days in public schools.

My life improved remarkably when I discovered art. The art world gave me a chance to express myself without words. I went to a workshop and gradually got good at making things with clay(黏土). Here I learned my first important lesson: disabled as I was in language. I could still be smart and well express myself with clay. And my confidence came along.

I got my next lesson from rock climbing. It was a fun thing but I was scared from the start. I soon noticed it wasn't a talent thing; it was practice. So I did it more. After about five years of climbing, I found myself in Yosemite Valley on a big wall. I learned that if you fall in love with something and do it all the time, you will get better at it.

Later I decided to apply my previous experience to learning how to read and write. Every day I practiced reading and writing, which I used to avoid as much as possible. After two hard years, I was literate.

Having gone through the long process with art, rock climbing, and reading and writing, now I've got to a point in my life where I know I am smart enough to dive into an area that is totally unknown, hard, but interesting.
