The Download: text-to-video AI, and China’s big methanol bet

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.

Meta's new AI can turn text prompts into videos

What's happened: Meta has unveiled an AI system that generates short videos based on text prompts. Make-A-Video lets you type in a string of words, like A dog wearing a superhero outfit with a red cape flying through the sky," and then generates a five-second clip that, while pretty accurate, has the aesthetics of a trippy old home video.

How it works: 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.

Why it matters: 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. But it also raises some big ethical questions. Read the full story.

China is betting big on another gas engine alternative: methanol cars

As the Chinese government works to reach ambitious carbon goals, the country has become a global leader in the adoption of electric vehicles. But that's not the only greener car alternative it's pursuing.

While methanol fuel has been discussed and piloted in China for a decade, its adoption has long lagged. Now the government is trying to accelerate the adoption of methanol cars, along with other state efforts in the last year to draft methanol car standards and support relevant industries, reaffirm its commitment to the alternative fuel.

This matters because, just like EVs, the technology could become both a commercial success and a political boost to China's climate-tech ambitions. Read the full story.

Can we find ways to live beyond 100? Millionaires are betting on it.

Scientists and biotech companies have been networking with uber-wealthy investors at a swanky conference in Switzerland this week, making the case for longevity science and anti-aging strategies. My colleague Jess Hamzelou, our senior biomedicine reporter, joined them, and got a peek at some of the most cutting-edge work in the field. Read about what she discovered.

The big story

Meet the wannabe kidfluencers struggling for stardom

December 2019

On YouTube, children can become millionaires-seemingly overnight, without trying. The highest paid of them, eight-year-old Ryan Kaji, made $22 million in 2018 by playing with toys on his channel Ryan ToysReview (now Ryan's World). There are now thousands of similarly famous child YouTubers: babies who have been vlogged since the moment of their birth, 10-year-old streamers showing off video-game tricks, teenage girls giving acne advice from their bedrooms.

Why do so many kids want to be YouTubers? Do they only seek fame, or is there more to it: creativity, community, and a future career? How are their parents helping them? And what happens if, after spending thousands of dollars or dropping out of school, it doesn't work out? Read the full story.
