For Zeng, a young Chinese woman, an hour scrolling Douyin, the domestic version of TikTok, has become a daily ritual. Livestreaming took off in China in 2016 and has since become one of the nation’s favorite pastimes. Zeng particularly likes one creator: “Lawyer Longfei.” Every day, Longfei answers her 9 million followers’ legal inquiries live. Many deal with how women should approach tricky divorce cases.
But in May, Longfei’s account went dark for 15 days, most likely because her content doesn’t match the state’s view on marriage. While Longfei’s account was eventually reinstated last month, her case reflects how many streamers are grappling with the Chinese government’s increasing willingness to weigh in on what’s acceptable.
A new policy document, the Code of Conduct for Online Streamers, released by China’s top cultural authorities on June 22, is designed to instruct streamers on what is expected from them. Having managed to operate under the radar so far, livestreamers are now facing the full force of China’s censorship machine—and future interventions could prove even more invasive.

Meta’s new AI can make video based on text prompts
Although the effect is rather crude, the system offers an early glimpse of what’s coming next for generative artificial intelligence, and it is the next obvious step from the text-to-image AI systems that have caused huge excitement this year.
Meta’s announcement of Make-A-Video, which is not yet being made available to the public, will likely prompt other AI labs to release their own versions. It also raises some big ethical questions.
In the last month alone, AI lab OpenAI has made its latest text-to-image AI system DALL-E available to everyone, and AI startup Stability.AI launched Stable Diffusion, an open-source text-to-image system.
But text-to-video AI comes with some even greater challenges. For one, these models need a vast amount of computing power. They are an even bigger computational lift than large text-to-image AI models, which use millions of images to train, because putting together just one short video requires hundreds of images. That means it’s really only large tech companies that can afford to build these systems for the foreseeable future. They’re also trickier to train, because there aren’t large-scale data sets of high-quality videos paired with text.
To work around this, Meta combined data from three open-source image and video data sets to train its model. Standard text-image data sets of labeled still images helped the AI learn what objects are called and what they look like. And a database of videos helped it learn how those objects are supposed to move in the world. The combination of the two approaches helped Make-A-Video, which is described in a non-peer-reviewed paper published today, generate videos from text at scale.
Tanmay Gupta, a computer vision research scientist at the Allen Institute for Artificial Intelligence, says Meta’s results are promising. The videos it’s shared show that the model can capture 3D shapes as the camera rotates. The model also has some notion of depth and understanding of lighting. Gupta says some details and movements are decently done and convincing.
However, “there’s plenty of room for the research community to improve on, especially if these systems are to be used for video editing and professional content creation,” he adds. In particular, it’s still tough to model complex interactions between objects.
In the video generated by the prompt “An artist’s brush painting on a canvas,” the brush moves over the canvas, but strokes on the canvas aren’t realistic. “I would love to see these models succeed at generating a sequence of interactions, such as ‘The man picks up a book from the shelf, puts on his glasses, and sits down to read it while drinking a cup of coffee,’” Gupta says.
The Download: Amazon’s home-guarding robot, and covid’s violent legacy
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
Amazon has a new plan for its home robot Astro: to guard your life
The news: Amazon announced yesterday that its home robot, Astro, will be getting a slew of major updates aimed at further embedding it in homes—and in our daily lives.
The details: The new features offer more home monitoring. Astro will be able to watch pets and send a video feed of their activities to users, for example. But the robot will also be able to wander around the house to keep an eye on rooms and entry points. Amazon also announced a new collaboration between Astro and the Ring home security camera system designed to protect areas outside the home from possible break-ins.
Why it matters: Ring’s approach to surveillance hasn’t been without controversy. It’s reasonable to ask whether combining Astro’s ability to roam around a house with Ring’s established surveillance system might create even more problems than either product did in their previous iterations.

The pandemic created a “perfect storm” for Black women at risk of domestic violence
Starr Davis was smitten when she met a handsome stranger with flawless skin and a wide smile in March 2020. He was charming and persistent; but their whirlwind romance took a major turn when she fell pregnant. His aggressive behavior started to make her uncomfortable, but he was the father of her child.
He became physically abusive a few weeks after she moved in with him. He forbade her from setting foot outside, saying it was to protect her and their unborn child from covid. With no friends or close family nearby for support, she suffered in silence.
Covid seems to have made things worse for many women experiencing violence at home. Anti-domestic-violence advocates point to dramatic increases in calls to shelters and support groups, and many care workers say this increase in domestic violence seems to have disproportionately affected Black women like Davis.

The big story
Why the balance of power in tech is shifting toward workers
Something has changed for tech giants. Even as they continue to hold tremendous influence in our daily lives, a growing accountability movement has begun to check their power. Led in large part by tech workers themselves, a movement seeking reform of how these companies do business has taken on unprecedented momentum, particularly in the past year.
Concerns and anger over tech companies’ impact in the world is nothing new, of course. What’s changed is that workers are increasingly getting organized. Read the full story.

How AI is helping birth digital humans that look and sound just like us
Jennifer: And the team has also been exploring how these digital twins can be useful beyond the 2D world of a video conference.
Greg Cross: I guess the.. the big, you know, shift that’s coming right at the moment is the move from the 2D world of the internet, into the 3D world of the metaverse. So, I mean, and that, and that’s something we’ve always thought about and we’ve always been preparing for, I mean, Jack exists in full 3D, um, You know, Jack exists as a full body. So I mean, Jack can, you know, today we have, you know, we’re building augmented reality, prototypes of Jack walking around on a golf course. And, you know, we can go and ask Jack, how, how should we play this hole? Um, so these are some of the things that we are starting to imagine in terms of the way in which digital people, the way in which digital celebrities. Interact with us as we move into the 3D world.
Jennifer: And he thinks this technology can go a lot further.
Greg Cross: Healthcare and education are two amazing applications of this type of technology. And it’s amazing because we don’t have enough real people to deliver healthcare and education in the real world. So, I mean, so you can, you know, you can imagine how you can use a digital workforce to augment. And, and extend the skills and capability, not replace, but extend the skills and, and capabilities of real people.
