Welcome to Tech News Briefing. It's Friday, February 6th. I'm Bel Lin for the Wall Street Journal. AI is everywhere, it seems. It's even at the Winter Olympics, which kick off today. In Mil. We look at how the technology is helping an Olympic snowboarder improve her signature move as she competes for gold. Then what happens when AI assistants start talking to each other? What was formerly the stuff of sci fi is now a reality. We'll discuss how Moltbook, a viral social network just for AI bots, got started and what it means for the future of human and AI interaction. But first, an AI model developed by Google DeepMind is giving athletes like the Olympic snowboarder Maddie Mastro new insights into how their bodies move. WSJ reporter Isabel Bousquet is here to explain how AI is helping Mastro perfect her trademark jump trick and whether we might see this tool expand beyond the Olympics. So, Isabel, what exactly did AI teach Mastro about how she could improve her jump trick?
Isabel Bousquet (1:29)
One of the most compelling things was that when she was landing the Crippler, which is a really signature trick for her, she's known for it, the AI pointed out that her arm was slightly raised above her head, and it shouldn't be that way because snowboarding is partially judged on style and aesthetics, and having your arms sort of level and controlled is an important part of the judging. So the AI pointed that out. She had never noticed it before, even from reviewing footage of herself. Her coaches had never noticed it before. And yet seeing it in this form, where the AI was specifically pointing out every single angle, was helpful for understanding that.

To me, that begs the question of how AI knows that Mastro could potentially get better in such specific ways.
Isabel Bousquet (2:18)
Yeah, it's actually really interesting how they captured the data on this. I would have thought the snowboarders would have been kitted out with a ton of wearables and biometrics, but actually it involves none of that. And it's just analyzing straight video footage. So it can be any video footage, historical video footage, whatever. And it's using this new type of AI model. It was developed by researchers at Google DeepMind. And the idea of this model is that it's purpose built for understanding the human pose and the way it tracks through 3D space over time. So the purpose built elements of that is helpful because a lot of AI models we have today, ChatGPT, et cetera. They struggle a lot with understanding the physical world and having spatial awareness.
