1 . Given how valuable intelligence and automation are, we will continue to improve our technology if we are at all able to. At a certain point, we will build machines that are smarter than we are. Once we have machines that are smarter than we are, they will begin to improve themselves. The concern is really that we will build machines that are much more competent than we are. And the slightest divergence (分歧) between their goals and our own could destroy us.
Just think about how we relate to ants. We don’t hate them. We don’t go out of our way to harm them. In fact, sometimes we take pains not to harm them. We step over them on the sidewalk. But whenever their presence seriously conflicts with one of our goals, we will kill them without hesitation. The concern is that we will one day build machines that, whether they’re conscious or not, could treat us with similar disregard.
The bare fact is that we will continue to improve our intelligent machines. We have problems that we desperately need to solve. So we will do this, if we can. The train is already out of the station, and there’s no brake to pull. If we build machines that are more intelligent than we are, they will very likely develop in ways that we can’t imagine, and transcend us in ways that we can’t imagine.
So imagine we hit upon a design of super intelligent AI that has no safety concerns. This machine would be the perfect labor-saving device. It can design the machine that can build the machine which can do any physical work, powered by sunlight, more or less for the cost of raw materials. So we’re talking bout the end of human labour. We’re also talking about the end of most intellectual work. So what would apes like ourselves do in these circumstances?
But the moment we admit that information processing is the source of intelligence, we have to admit that we are in the process of building some sort of god. Now would be a good time to make sure it’s a god we can live with.

2 . “The past is a different country; they do things differently there," L.P. Hartley wrote in one of his best-known novels, The Go-Between. To the British novelist, the past was irrelevant. And one of my Chinese students once told me "I have no interest in the past. I'm only interested in the present and the future." I have to disagree. The "past" is a very interesting country, and the more we know about it, the more we will be able to understand the present and thus, prepare ourselves for the future.
An ideal place, as I see it, that can allow us to look back on the past is the museum. I prefer to visit museums as if you are sitting in the same room with some of the greatest men in history. While no museums can claim to offer a complete picture of human history, the lessons we can learn from the events and wonders of the past are of great value.
Thanks to modern technology, museums are being transformed from places of looking and learning to spaces of participation and interaction. A large number of immersive (沉浸式) multi-media displays, which allow visitors to engage with its exhibits during their visit, play a big part at the Shanghai Natural History Museum.
The rise in technology has also made museums more accessible than ever. Since the outbreak of COVID-19, traditional museums have started to think outside of the box in order to create new ways for visitors to experience their collections online. It is definitely good news for those who are fascinated by museums but are struggling to actually go there. However, you shouldn't expect to get the same experience that an in-person visit would provide, at least, that is, for now.
International Museum Day is observed on May 18 every year. This is a quick reminder that you should always spare some time to visit museums and appreciate the "must-see 'em" things that are an important part of the cultural heritage of humankind.

3 . By mid-century there will likely be 9 billion people on the planet, using ever more resources and leading ever more technologically complex lives. What will our cities be like? How much will artificial intelligence (AI) advance? Will global warming cause disastrous changes, or will we be able to engineer our way out of the climate change issues? Recently, the magazine Big Think asked top minds from a variety of fields to weigh in on what the future holds 40 years from now. The result is as follows.
It's likely that by 2050 the majority of the people in the world will live in urban areas and will have a much higher average age than people today. Cities theorist Richard thinks urbanization will transform the education system of, making our economy less houses driven and removing the divisions between home and work.
And rapidly advancing technology will continue ever more rapidly. Cities of the future won't look like “some sort of science-fiction fantasy”, but it's likely that technological advances and information overlays (VR and AR) will greatly change how we live. Self- driving cars will make the roads safer and provide faster transports. A larger version of driverless cars-driverless trucks — may make long-distance drivers out of date.
Some long view predictions are completely dire. Environmentalist Bill says that if we don't make great progress in fighting global warming, it's likely we could see out-of- control rises in sea levels, huge crop shortfalls and wars over limited freshwater resources.
In terms of how we will eat, green markets founder and “real food" supporter Nina believes that there will be more small milk processing plants and more regional food operations and we'll be healthier as a result. New York Times writer Mark thinks that people will eat fewer processed foods and eat foods grown closer to where they live. And more people will be aware of the ethical responsibility" to grow foods.

4 . With over 4.1 billion people, or around 55 percent of the world’s population, living in urban areas, cities and towns worldwide are getting increasingly jammed. In addition to spending hours stuck in traffic, residents are also exposed to high air pollution levels caused by transportation emissions(排放). Now, Saudi Arabia hopes to overturn urban living with “The Line”—a futuristic city designed around nature, without cars, roads and crowded places!
The totally different city, announced on January 10, 2021, is the brainchild of Saudi Crown Prince(王储)Mohammed bin Salman(MBS).Located in Neom, a 10, 000-square-mile high-tech planned development on the Red Sea coast. The Line will be the base of MBS’s Saudi Vision 2030. The strategic plan aims to diversify Saudi Arabia’s oil-dependent economy into other fields, like tourism, and create exciting job opportunities for its citizens.
The 105-mile-long city, expected to cost between $100 billion and $200 billion, will be built along a straight line and comprise several self-sustaining communities. To ensure all services are within a short, five-minute walk, each community will feature a three-layer infrastructure(基础设施)．
There will be no cars or roads on the top “pedestrian layer”, so residents can freely walk and bike in the surrounding green spaces. The second “service layer”, will include all essential daily services, such as schools, medical clinics, leisure facilities, and grocery stores. The third “spine layer” will house ultra-high-speed transportation and autonomous vehicles transporting residents across communities in less than 20 minutes. The entire city will be powered with renewable clean energy sources such as solar and wind, and possibly even hydrogen．
If all goes according to the plan, construction of this groundbreaking, complex infrastructure project will start before the end of 2021. In addition to providing up to a million residents with a clean and stress-free living environment, the Line is expected to create 380, 000 new jobs, promote economic diversification, and contribute a shocking $48 billion to Saudi Arabia’s Gross Domestic Product(GDP)by 2030. More importantly, MBS believes it will provide governments worldwide a blueprint for how people and planet can co-exist in harmony.

5 . Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict.” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes—khaki pants and a sports shirt—to the office. He hardly ever wears a necktie. “I am working harder than ever.” David says, “and I need to feel comfortable.”
More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday (but only on Friday). This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.” said business consultant Maisly Jones.
Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code.” “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative(保守的)dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss and Company, 85 percent of employers said that they believe that casual dress improves employee morale(心境，士气). Only 4 percent of employers said that casual dress has a negative influence on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”
