In recent years, artificial intelligence has made a deep (impress) on our daily lives and work. This (power) technology, has developed rapidly across the globe, is now being widely used in many important fields including education, healthcare, and transportation. It has become an essential tool that helps people solve complex problems and improve work efficiency.

Since it first entered our lives, AI (bring) numerous benefits to modern society. For instance, it helps doctors make more accurate diagnoses and assists students in learning more effectively. (obvious), this revolutionary technology has significantly improved our living standards in various aspects. However, we must also recognize that it brings certain challenges that require immediate attention and careful consideration.

Technology companies and developers should be responsible establishing comprehensive guidelines and ensuring their AI systems are used in correct and ethical ways. Current AI systems, (know) for their extraordinary capacity to process and analyze vast amounts of information within seconds, sometimes generate (confuse) or even contradictory results that may mislead users.

In a recently published scientific study conducted by leading experts from multiple countries, this particular problem (refer) to as "the AI Reliability Challenge". Researchers emphasize that both technical specialists general public need to collaborate closely to address these issues and make artificial intelligence more secure, trustworthy, and beneficial for all humanity in the future.

The answer is largely that people were becoming better nourished and mentally stimulated. Just as muscles need food and exercise to grow strong, the brain also needs the right nutrients and activity to develop. Kids today are much less likely to be malnourished (营养不良的) than they were in past decades, and more likely to go to school. Yet there is no room for satisfaction. In poor and middle-income countries, many children are still too ill-fed to reach the cognitive potential.

The world grows enough food, but several obstacles stop nutrients getting into young brains. One is war. Families sheltering around cannot risk out to plant or harvest, and some governments intentionally starve certain regions into submission. Another is disease. Hungry children fall sick more often, and the energy they spend battling bugs cannot be devoted to growing brains. Poverty is also a big part of the problem. But global data from UNICEF, an aid agency, show that although half the children with very restricted diets (including no more than two food groups) are indeed from poor families, the other half are not. Other factors, such as poor eating habits, are to blame as well. Research about how to overcome the obstacles is needed.

Some argue that human intelligence will matter less as people entrust (委托) their thinking to artificial intelligence. To assume this would be as foolish as betting 100 years ago that the invention of the car would make it unnecessary to walk. In the workplace, human intelligence and AI will probably assist each other. And brains are for the joy of thinking, as well as earning money. Steven Pinker of Harvard University calls human intelligence "a tailwind in life", helping people adapt rationally to new challenges or a changing environment. For a modest price, the next generation can have a stronger tailwind. It would not only be wrong to refuse them the tailwind. It would be stupid.

Personality is the pattern of thoughts, feelings and behaviors unique to a person. People always think of personality as fixed. But according to psychologists, that's not how it works. "Personality is developing. It's not just something that you're stuck with and can't get over," said Brent Roberts, a psychologist at the University of Illinois.

That's not to say that you're a different person each day you wake up. In the short term, change can be nearly impossible to see, Roberts told Live Science. Longitudinal studies, in which researchers survey the personalities of participants regularly over many years, suggest that our personality is actually stable in the short term.

But those years add up, throughout which our personality is still changing, but slowly, Roberts said. "It's something that's unnoticeable," he added. You don't feel it on that five-to-10-year time period, but in the long term, it becomes obvious. In 1960, psychologists surveyed over 440,000 high school students — around 5% of all students in the country at that time. The students answered questions about everything from how they behaved in emotional situations to how well and effectively they got work done. Fifty years later, researchers tracked down 1,952 of these former students and gave them the same survey. The results found that in their 60s, participants scored much higher than they had as teenagers.

Some people might change less than others, but in general, the maturity (成熟) principle goes for everyone. That makes personality change even harder to realize in ourselves — how your personality compares with that of your peers doesn't change as much as our overall change in personality, because everyone else is changing right along with you. "It has been proved that the self-control of a 30-year-old is higher than a 20-year-old," Donnellan said. "At the same time, people who are more self-controlled at 18 are also possibly more self-controlled at age 30."
