1、The average person must think the field of artificial intelligence or AI is making great progress. The boss of a top tech company thinks that in search of creating AI that has the flexibility of the human brain, "the game is over". Don't be fooled. We should see it in a reasonable way. Machines may someday be as smart as people and perhaps even smarter, but the game is far from over. There is still a large amount of work to be done in making AI machines that can truly understand and reason about the world around them. What we need right now is more basic research to speed it up.

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.

2、Farming was considered part of the rural charm in the past. But now, farms have come to the concrete jungle and they can even be found high up on balconies. According to a recent report released by Chinese e-commerce platform Alibaba, the sales of vegetable seeds on Tmall doubled in the first quarter compared with the same period last year. Sales of products such as nutrient soil and gardening tools have tripled since April of last year. Out of all the people buying farming tools and seeds, most were born after 1995.

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.
