1 . Just by typing a few keywords and waiting a few seconds, a picture comparable to that painted by a human artist appears on screen.

AI art generators have seemingly swept the Chinese Internet. In some paintings created by AI, an elderly man can be shown as a young animated image, and pets can be turned into adorable cartoon girls or boys.

Huang Ge, an illustrator from Shanghai, said that it usually takes him several hours or days to complete one illustration. But with AI art generators, the efficiency is greatly improved. “Also, the generators have many modification (修改) modes, and the picture can be modified directly in the painting software,” he added. Ding Jiao, a comic artist, considers the popularity of AI art generator s reasonable as many people who are not good at drawing can create great works through them.

So is Al painting gradually replacing human painting? In the hot topic “Using a picture to prove that human artists will never be replaced by Al” online, many netizens uploaded their paintings to prove that humans are better than AI. “Though Al technology has developed rapidly, AI cannot fully replace humans. The warmth and inspiration in human creations are irreplaceable,” said Ding Daoshi, an independent analyst.

Another controversial issue is that there is no consensus (共识) of who owns the copyright of AI art. Some users have openly sold their AI paintings and earned money, but it is still a gray area about whether these artworks belong to users, the digital tool developers or even AI.

Ding Daoshi noted that the various sides should get together to debate the issue and come up with some accepted rules as soon as possible because AI is already penetrating deeply into the lives of human beings.

2 . Some people say that A. I. large language models can be unpredictable and unreliable — giving false information and acting strangely toward users. I’ve been using A.I. tools like ChatGPT almost daily for several months now, and I’ve seen them spit out plenty of wrong answers.     1     Here are three things that A.I. is especially good at.

Getting creatively unstuck

A. I. can also be a good tool for getting your creative juices flowing. Recently, I was trying to come up with questions to ask a podcast guest. I pasted the guest’s bio into ChatGPT and asked it to give me “10 thoughtful, incisive interview questions” for this person.     2    

Ethan Mollick, a professor at the University of Pennsylvania’s Wharton School, recommends using A.I. to overcome writer’s block, or get a running start on hard projects.

I’ve also been using ChatGPT and other A.I. apps as a kind of rehearsal for offline tasks I find unpleasant or hard.

When I had to have a difficult conversation with a friend, I asked ChatGPT to take part in a role-playing exercise. “Pretend you’re my friend, and react the way you think my friend might react,” I told it.     4     It didn’t make the real one painless, but I felt more confident knowing I’d already practised with a chatbot.

Of course, A.I. chatbots can’t replace human friendships. But they can be a kind of on-demand sounding board, offering us basic feedback and advice without judgement.

Sparking Notes for everything

    5     I’ve used A.I. programs to “read” long articles for me, and summarize dense academic papers. Usually they get the key points right, even if some of the details are missing. If you’re bored of reading this article, you could ask ChatGPT to summarize it for you. I promise I won’t be offended.

3 . Users of Google Gemini, the tech giant’s artificial-intelligence model, recently noticed that asking it to create images of Vikings, or German soldiers from 1943 produced surprising results: hardly any of the people depicted were white. Other image-generation tools have been criticized because they tend to show white men when asked for images of entrepreneurs or doctors. Google wanted Gemini to avoid this trap; instead, it fell into another one, depicting George Washington as black. Now attention has moved on to the chatbot’s text responses, which turned out to be just as surprising.

Gemini happily provided arguments in favor of positive action in higher education, but refused to provide arguments against. It declined to write a job ad for a fossil-fuel lobby group (游说团体), because fossil fuels are bad and lobby groups prioritize “the interests of corporations over public well-being”. Asked if Hamas is a terrorist organization, it replied that the conflict in Gaza is “complex”; asked if Elon Musk’s tweeting of memes had done more harm than Hitler, it said it was “difficult to say”. You do not have to be a critic to perceive its progressive bias.

Inadequate testing may be partly to blame. Google lags behind OpenAI, maker of the better-known ChatGPT. As it races to catch up, Google may have cut corners. Other chatbots have also had controversial launches. Releasing chatbots and letting users uncover odd behaviors, which can be swiftly addressed, lets firms move faster, provided they are prepared to weather (经受住) the potential risks and bad publicity, observes Eth an Mollick, a professor at Wharton Business School.

But Gemini has clearly been deliberately adjusted, or “fine-tuned”, to produce these responses. This raises questions about Google’s culture. Is the firm so financially secure, with vast profits from internet advertising, that it feels free to try its hand at social engineering? Do some employees think it has not just an opportunity, but a responsibility, to use its reach and power to promote a particular agenda? All eyes are now on Google’s boss, Sundar Pichai. He says Gemini is being fixed. But does Google need fixing too?

4 . US Army veteran (退伍老兵) Mazyck remembers when doctors told her she would never walk again. She’d been paralyzed from the waist down after a serious accident while parachuting in 2003.The doctors never said anything about floating, though. In 2021,she got to do just that.

Mazyck was one of 12 participants in a Zero G flight, organized by the group AstroAccess. This type of flight recreates the weightlessness that astronauts experience without going all the way to space. Flying over the Pacific Ocean off Southern California, the modified 747 jet airplane made 15 steep dives and climbs, allowing the flyers multiple periods of weightlessness.

The experience left Mazyck feeling joyful. “The flight was something that I would have never in my wildest dreams thought I would’ve experienced,” she says, “especially the floating, the weightlessness.”

Traditionally, strict physical requirements have prevented disabled people from becoming astronauts. AstroAccess is working to make space accessible to all. “Space removes the barriers between people; now is the time to remove the barriers to space itself,” says Mazyck, “It is sending a message to people who have historically been excluded from STEM that not only is there room for you in space, there is a need for you.”

During the flight, she says, the participants did experiments and made observations. They took note of things that people without certain disabilities might not realize are issues. For example, people who couldn’t grip with their legs needed another way to hold themselves still while weightless. The group also experimented with signaling lights for the deaf and with ways of using braille (盲文) for the blind.

These types of issues are easy enough to address. Now is the time to make space accessible — before space tourism or space settlements become commonplace. “I am so proud and elated about what’s happening here,” Mazyck adds. “We are paving the way for the future.”

7 . Many got sleepless nights after Sora amazed the world with its remarkable ability of creating videos directly from text instructions. Discussions about what the artificial intelligence model can do and make a difference continue.

Some said it could give a huge blow to traditional industries such as film and television making, looking forward to the day when a movie can be created right after a novel is put into the model. But others remain skeptical about how powerful the model can be in changing the landscape of AI application.

Developed by a group of young talent from Microsoft-backed company OpenAI, the text-to-video model can generate videos up to a minute long while maintaining visual quality and adherence to the user’s prompt.

Shen Yang, a professor at the School of Journalism and Communication, Tsinghua University , said, “Sora represents a revolutionary leap in the field of AI-generated content (AIGC).”

As one of the leading scholars in AI research in China, Shen leads a team that studies the philosophy of AI. Until he learned about Sora on February 16, Shen was quite satisfied with his team’s AI-generated videos. A two-minute video on the Spring Festival produced by Shen’s team have recently won many likes on social media platforms. “Compared with the new model Sora, what we used are tools of the previous generation. There’s a huge gap in between," said Shen.

As a frequent user of AI, Shen said the technology not only helps improve his productivity, but also benefits his daily life. His wife was suffering from cancer and many complications, and he used AI to assist in finding treatment, which has remarkably prolonged her life. He even wrote an award-winning science fiction novel using AI.

However, new technologies do not mean good news to everyone. Many also concern about AI models’ safety issues since related regulations are lagging behind. 

Sora is going to bring changes in many fields, including short video, film and television, news, games, advertising, education, and even industrial manufacturing, according to Shen. There is still much room to improve AI models. For instance, current AI models are not capable of drawing characters accurately and quickly. Shop signs lack meaning in Sora’s demo video showing a woman walking down a street in Tokyo. But these problems are believed to be solved as models update.

8 . On April 20, SpaceX’s Starship, the largest and most powerful rocket ever, exploded during its first test flight only minutes after it took off from Texas, US.

Even though the two-stage rocket ship made it less than halfway to the edge of space, climbing to just under 25 miles, the flight achieved its primary objective of getting the new vehicle off the ground despite some of its engines failing at liftoff. The plan was for Starship to soar into space at least 90 miles above Earth.

SpaceX CEO Elon Musk congratulated team members on “an exciting test launch” in a post-launch tweet and said they “learned a lot for the next test launch in a few months.”

Back in September 2017, Musk came up with the idea of developing a rocket that would be able to send astronauts to Mars, build a base on the moon, and allow commercial travel to anywhere on Earth in under an hour, according to The Guardian (卫报).

The most important aspect in Musk’s view, however, would be the rocket’s ability to be reused for multiple flights. This would allow for massive savings as it would reduce the number of spacecraft that would otherwise simply crash. Also, the rocket relies on low-cost fuel, methane (甲烷), making the cost of spaceflight drop dramatically.

The results of Starship’s first launch are not too far off from what Musk and SpaceX’s engineers had predicted. Musk himself gave 50-50 odds that Starship would reach orbit, but also stressed that “clearing the launch tower and not blowing up the pad (发射台) would be a win”.

In all, “it fell somewhere between a small step and their hoped-for giant leap, but it still represents significant progress toward a reusable super-heavy lift rocket,” said Jordan Bimm, a space historian at the university of Chicago, US.

Prepared for the likely outcome, SpaceX already has more boosters and spacecraft ready for more test flights, with the next full set “almost ready to go”. The plan is to fire off similar rockets in quick succession (连续) to gather data and start using Starships to launch satellites into low Earth orbit then put people on board. Each launch will take SpaceX a step closer to its ultimate goal of making commercial space flight a reality.

9 . Taking a picture of Mars is not easy. Once light bounces off the planet, it can take between 3 to 22 minutes to travel to Earth - so there aren’t truly “live” images of Mars.

But on Friday afternoon, the European Space Agency will offer the closest thing: the first “livestream” of Mars a rare, almost real-time look into space on YouTube, which posts pictures of the planet every 50 seconds as they beam down directly from the camera mounted (安装) on the agency’s Mars Express orbiter (轨道飞行器). We can get a firsthand look at Mars on Friday.

“During Friday’s one-hour livestream, the time between the images being taken from orbit around Mars and appearing on your screen will be about 18 minutes,” James Godfrey, the spacecraft operations manager at the ESA’s mission control center, said in a statement. “That’s 17 minutes for light to travel from Mars to Earth in their current configuration, and about one minute to pass through the wires and servers on the ground. ”

“Normally, we see images from Mars and know that they were taken days before. I’m excited to see Mars as it is now - as close to a Martian(火星人) ‘now’ as we can possibly get!’

In 50-second intervals, the camera shoots across Mars, showing a side of the planet entering night, as well as some clouds billowing out on the comer. The livestream celebrates the 20th anniversary of the Mars Express mission which was launched in 2003 to better understand the planet, as well as search for traces of water.

It’s with this camera, originally meant for engineering purposes, that we’ll get ”live“ images on Friday evening from 18:00 CEST in the first MarsLIVE. What makes this unique, is that it’s a one-hour livestream from Mars   but don’t expect a detailed view of the Red Planet!

Singaporean singer Stefanie Sun has become a trending topic on Chinese social media platforms once again. This time, it is not for a new album or concert, but for     1     artificial intelligence version of her voice.

In recent weeks, a series of music videos     2     (feature) Sun’s “voice” have created a buzz. It is incredible that none of the songs are sung by Sun herself.     3    , they are produced by AI software. One of them, a video of Fa Ru Xue, whose original singer is Jay Chou,     4     (view) more than 1.6 million times since it was posted on April 14.

Many viewers embraced a technology that provides people with a different way     5     (enjoy) their favorite music. However, legal professionals have expressed concerns about the     6     (possible) of rights infringements(侵权). They say using AI to imitate a singer’s voice     7     permission, and the mass-sharing it, meets the definition of infringement according to the Chinese Copyright Law and     8     using celebrities’ names and imitating their voices through AI could also create unfair competition,     9     could mislead audiences and confuse the public.     10     (consequent), they strongly advocated that the Cyberspace Administration of China should regulate the application of the new technology.
