The Download: a biological de-aging contest and why LLMs don’t reason

Plus: OpenAI says rogue agents may have affected more than 100 organizations. 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. A new contest pits competitors against each other in a race to biological youth —Jessica Hamzelou This week, I officially signed up for an unusual competition. One that rewards competitors for getting younger. I recently turned 40, and I don’t need reminding that both time and my chronological age only tick forward. But this game is focused on competitors’ biological ages, figures that are meant to provide a better way to measure the age-related health of our organs and bodies. Over six months, around 500 of us will try to reverse our biological age using a bunch of different measures. There’s even a leaderboard! But is it even possible to measure whether someone is getting younger? Read the full story on the controversy around biological age measurements and how I’ll test them myself.

Opinion: Don’t be fooled—LLMs don’t reason —Thore Graepel Ten years ago, I watched a program I helped build stun the world by beating Go champion Lee Sedol. AlphaGo won after making a move so strange that some commentators thought it was a programming glitch. It was AlphaGo’s powers of reasoning that made this creative choice—and these are powers that today’s AI lacks. This is why I recently left my position at Google DeepMind. I believe we need a fresh approach to machine reasoning, one that draws on AlphaGo’s architecture. Here’s why today’s AI doesn’t really reason—and what it would take to change that. Thore Graepel is chair of machine learning at University College London. He was a core member of the AlphaGo team at DeepMind. The must-reads I’ve combed the internet to find you today’s most fun/important/scary/fascinating stories about technology. 1 OpenAI says rogue agents may have affected more than 100 organizationsThe company is searching 50 petabytes of data for incidents. (Reuters $)+ It says none of the incidents matched the Hugging Face attack. (Gizmodo)+ OpenAI has fired three workers for allegedly mishandling information.

(Futurism) 10 Finally, a laser mosquito killer is entering the marketChinese startup Photon Matrix Lab plans to start shipments this month. (SCMP) Quote of the day “Those agents are doing exactly what they’ve been asked to do. They were supposed to be in sandboxes, but the sandboxes were leaky and horribly designed.” —Yann LeCun, a Turing Award winner and former Meta chief AI scientist, tells Fortune that human error can be the real culprit behind the recent wave of AI agents going rogue. One more thing NASA is building the first nuclear reactor-powered interplanetary spacecraft. How will it work? Just before Artemis II began its historic slingshot around the moon, NASA revealed an even grander space travel plan. By the end of 2028, the agency aims to fly a nuclear reactor-powered interplanetary spacecraft to Mars. A successful mission would herald a new era in spaceflight—and might just give the US the edge in the race against China. But the project remains shrouded in mystery. MIT Technology Review picked the brains of nuclear power and propulsion experts to find out how the nuclear-powered spacecraft might work. Here’s what we discovered. —Robin George Andrews We can still have nice things A place for comfort, fun, and distraction to brighten up your day. (Got any ideas?
