AI is making progress. Artificial images look more and more realistic, and speech recognition can often work in noisy environments. But we are still likely decades away from human-level AI that can understand the true meanings of articles and videos or deal with unexpected difficulties. The field is stuck on the same challenges that scientists have been pointing out for years: getting AI to be reliable and getting it to flexibly deal with unusual situations. Unluckily, the fact is that these systems still fail to work reliably and struggle with new situations.

Although deep learning has advanced the ability of AI machines to recognize patterns in data, it has three main disadvantages. The patterns that it learns are superficial. The results it creates are hard to explain. And the results are difficult to use in the other processes, such as memory and reasoning. As Harvard University computer scientist Leslie Valiant noted, "The central challenge in the future is to unify the formulations (统一公式) of learning and reasoning." You can't deal with a person carrying a stop sign if you don't really understand what a stop sign even is.

It's time for AI researchers to get out of turning to the media straightly for help, and ask important questions about how to build systems that can learn and reason at the same time.

Zhang Chao, a 17-year-old senior high student from Anhui province, is one such young "urban farmer." His love for planting grew when he lived with his grandpa in the countryside during primary school. His grandpa, a lifelong farmer, enjoyed planting seasonal vegetables in their backyard garden. Zhang was inspired by his grandpa's passion and learned to grow his own vegetables. Despite the hard work of ploughing, fertilizing, and watering, Zhang felt a great sense of achievement when he saw his seeds turn into plants. "It brings back good memories," he said. Though Zhang now lives in an apartment without a yard, he continues his hobby with a balcony garden. He has bought strawberry and tomato seeds. "Growing fruits and vegetables not only provides delicious food but also reminds me of the happy times with my grandpa," he added.

Fang Minke, a 16-year-old girl from Shenzhen Foreign Languages School, sees gardening as a way to relax and develop patience. With many academic responsibilities, she often feels stressed. To add some color to her life, she started planting vegetables on her balcony in 2021. Most of the seeds were given by her friends. She plants them without knowing exactly what they are and waits patiently. After half a year, her balcony became a small garden with flowers and herbs like coriander. After long hours of homework, she enjoys walking around her balcony garden. "It makes me feel closer to nature and refreshed," she said. "Even if the vegetables and herbs are not our main food, they add flavor to our dishes and brighten our busy days."

Planting vegetables is now more than just a way to survive. It also brings joy and purpose to young people's lives.

The Popsicle Kids

A nearly empty box of Popsicles (棒冰) in the freezer, left from a grandchild's visit, caught my attention. Initially, I wanted to throw it away, but my wife suggested we give the remaining Popsicles to the neighborhood children. Her suggestion changed our life and led us to a future full of "Popsicle Kids." My wife and I, retired on Social Security, live in an apartment complex. After careers in sales and nursing, our daily concerns revolved around aches, pains, and dinner. We often wondered what good we were to the world.

That changed dramatically after we gave away the first Popsicle.

Minutes after watching a neighbor boy, a second grader, walk away with an icy treat, our doorbell rang. An adorable blond girl, about six, smiled sweetly, "Is it true you're giving away Popsicles?"

With the box empty, we returned to our concerns.

Early the next morning, the doorbell rang repeatedly. Standing on our porch were the four children from the previous day. They vocalized their wants, chanting (有节奏地喊), "We want Popsicles! We want Popsicles!"

Looking into their eager young faces, I wondered, "What have I started?" Sensing a victory, they nodded eagerly when I explained the rules: ring the bell once, one Popsicle per day, and share something good about their day. But their thin shoulders bent downwards in disappointment when I mentioned they had to give something in return. I came to the rescue, suggesting they share something positive about their day, like what they learned at school or helping another student. Over time, new rules were added: "Ladies first," "Don't interrupt," and "Properly get rid of the sticks."

On holidays, they expressed their understanding of why the day was celebrated. Over the years, about fifty youngsters visited. Some became part of my life, like the four kids who joined me on the steps one spring to read "Where the Red Fern Grows." We discussed catching crawfish, loving pets, and family relationships. This simple act of sharing Popsicles transformed our life, bringing joy and meaning to both the children and ourselves.

The hulusi, with a history that can be traced back to the pre-Qin period in China, originated in the southwestern border of China, especially among ethnic minorities such as the Dai, Achang and Blang in Yunnan, is an essential musical companion in their cultural life.

The structure of the hulusi is unique, mainly (compose) of three parts: a natural gourd (葫芦), three bamboo tubes, and a built-in reed (簧片). The selection of the gourd is crucial, requiring uniform shape and a solid layer to produce a good effect. Bamboo tubes and reeds are particularly carefully made, with the length of the bamboo tube and the thickness of the reed needing to be adjusted according to the pitch (音高) (ensure) that every note can be clearly and accurately produced.

The tone of the hulusi is gentle and delicate, like a soft breeze (blow) in the mountains, giving people a subtle and misty beauty. Whether it is folk songs, farm songs, or folk tunes, the hulusi can bring the audience into a quiet and distant (art) conception with its unique tone, soothing people's hearts and conveying the harmony and quietness of nature.

The hulusi is not only a unique musical instrument but an important (carry) of ethnic culture in local weddings, funerals and sacrificial activities, the melody of the hulusi often rings, conveying the feelings about life of the ethnic group. In recent years, with the emphasis and promotion of ethnic culture, the hulusi (receive) more and more attention in China and shown its unique charm on the international stage, attracting the attention of music lovers around the world.

"Dad, don't leave the water2 when you brush your teeth," Nathaniel told me seriously on our first night. All right. I figured, this is California, where3 is a concern. But when I grabbed extra paper towels to4 the kitchen counter, he instructed me to use the dishcloth. Over the following days, more "5" came: don't leave heavy walking shoes scattered, no need for a scarf when walking the dog in the morning, not too much soda...

Then I remembered the golden rule of6 when Nathaniel and his siblings (兄弟姐妹) were young. "Someday, you'll have a home of your own and can live however you want," I'd say. "7, you'll have to do as we ask." Now it was payback time.

Remembering how much I disliked my father's commands as a child, I now smilingly8 Nathaniel's "household laws". There were special9 to playing beta (从属角色) to Nathaniel's alpha (主导角色). He cleaned dishes after dinner, set our daily outings, and willingly drove everywhere...

Our dramatic role10 revealed another side to my elder boy, giving me hope for his future parenting ability. Last afternoon when walking along Matador Beach, we hit a patch of rocks. I was11 and wouldn't go any further, but Nathaniel guided me across one large stone to the next,12 telling me where to place my feet and hands as ocean waves came close. After a couple hundred yards we13 to a fresh sandy stretch.

"You did it! I'm really14," he said, beaming, as if I'd just learned to ride a bike. It was then that I knew for sure that the son would also rise to15.

Right now, people are focused on AI potentially causing job losses. George Stakhov said, "By 2050, AI will have profoundly reshaped the world. It is very likely that there is a dark AI future where those who control AI will gain huge power, while 99 percent of the population will be deprived of their rights. The AI masters will control the world's data and turn the rest of us into their slaves. In that case, everyone benefits from AI through better healthcare, faster transport and less pollution."

Futurist and former Google engineer Ray Kurzweil says that people will have integrated with machines by 2025 and predicts that by 2045, people will have connected their brains to machines, integrating with the intelligence created.

That means we could be in contact with aliens. Shostak said that newer measurements suggest that there could be billions of Earth-like worlds. That may be the strongest argument for life in space.

Rising humidity (湿度) and heat will lead to heatwaves where it is almost impossible for humans to survive in areas including South Asia and the Red Sea. Humans can survive temperatures of up to 50 ℃ when humidity is low, but in high humidity, humans cannot survive because there is no way to cool down by sweating. Even extremely strong and fit people die within hours. Large areas of the Earth might be uninhabitable.

​​​​​​​A. The alternative is a bright AI prospect.

B. However, the reality could be far worse.

C. Actually, AI brings far more benefits than harm.

D. This means that the Earth is the only place with life.

E. By 2070, this will also be true in areas of Brazil and China.

F. Thus, people will increase their effective intelligence a billion-fold.

G. Alien-hunting astronomer Shostak bets we should find aliens within two dozen years.

Over 500 million people visit American public lands each year, creating many chances to harm wild places. "When you look at the numbers, it's incredible," says Watts, head of the Leave No Trace Center in Colorado, an organization aimed at minimizing human impact on nature.

Food waste takes a long time to break down, especially in certain areas. "It takes much longer for an applet core to rot in a desert than in a forest." says Blye, a teacher at the University of Utah, Leaving waste introduces animals to an unnatural diet and changes their behavior with sometimes disastrous results. Bears who taste garbage and become a threat to humans may have to be put down. "Bears can get used to unnatural food in three weeks," says Watts. "Everyone loses in this case."

Biological waste is also problematic. Dog waste brings new bacteria into the ecosystem and scares away deer. Meanwhile, human waste and toilet paper introduces dangerous bacteria into water sources.

In national parks, trails (小路) are designed to avoid sensitive areas. Stepping off the trail, even for a quick photo, can scare wildlife away. Impacts from many visitors result in long-term damage to nature and wildlife. But people don't think of that when they see the perfect photo opportunity. "It's just such a hard thing to resist," says Blye. The risk to sensitive ecosystems isn't obvious. "It's easy to think, oh, there's wildflowers over there. I shouldn't step on that," says Blye, but these tiny ecosystems full of microscopic organisms essential to desert life provide many benefits, including reducing the risk of erosion (侵蚀) and helping absorb rainfall, and can take hundreds of years to return to its original state.

A single micro-farm takes up only 15 square feet, but has the productivity of around 2,000 square feet of outdoor farmland. And since each farm is remotely managed by our team, anyone can grow amazing produce no matter their level of skill.

To get started, tell us what your favorite produce items are, and we'll create a tailored growing program for you and you can start enjoying fresh food all year. Operating your farm is simple and easy. You choose from our wide selection of salad mixes, herbs, flowers and micro-greens, and we'll deliver them to you ahead of time and ready to grow.

Your personal account manager will make sure you have everything you need, from helping you install (安装) the app on your phone to providing your seeds. When your seed packets arrive, all you have to do is place them into your farm and scan their codes using the app. Once you scan a crop, the app will take over managing a unique growth recipe for that specific crop and let you know when to transplant and harvest.

Micro-Farms makes scheduling harvests easy, while your personal account manager ensures you get the most value from your investment through custom programs. You can create a unique engaging community and team-building experiences, host special events and enjoy seasonal menus.

After harvest, Micro-Farms will send you new seeds and supplies to keep your farm running at maximum productivity. We can connect multiple farms toscale productivity to suit your specific needs. The farms work together in harmony through the Cloud to provide reliable yields all year around.

"It's halfway crazy," she says. A house swap she was interested in didn't work out, but the owner, Rachele, asked: "‘Do you know anyone who might help me with the children?' I wrote back and said: ‘Tell me what that involves!' She wrote me a little list, and I said: ‘I could do that!' We seemed to believe in each other."

Two months later, when Faulkner reached Varese, "the dad, Andrea, was walking towards me with the children hiding behind his legs, kind of shy, thinking: ‘Who is this woman in a long black coat?' I don't think it was quite Mary Poppins, but the atmosphere was immediately warm and friendly."

Eighteen months on, Faulkner's job no longer feels like a job. "I just feel like part of the family." They joke: "You think you're going back to Scotland? No, you're staying here!" She gives English lessons, helps with the housework, meets the children from school, plays chess or table tennis with them, and takes them to the park. "It never feels like work," she says. "It has been absolutely the perfect match." Faulkner's son, Steven, who lives in London, has visited her and they have cycled around the northern Italian lakes. She feels no more distant than when she lived in Edinburgh.

"You have to take the opportunity when it presents itself," Jim once said.

"I'll be 70 in January, but in my head, I'm 30. I still feel the same person, I have the same enthusiasm for life, the same interest in people and things. In that sense, I wish I had another 70," Faulkner jokes.
