Plus: Anthropic won't bow to the US government's demandsFebruary 27, 2026 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. AI is rewiring how the world’s best Go players think Ten years ago AlphaGo, Google DeepMind’s AI program, stunned the world by defeating the South Korean Go player Lee Sedol.And in the years since, AI has upended the game. It’s overturned centuries-old principles about the best moves and introduced entirely new ones. Players now train to replicate AI’s moves as closely as they can rather than inventing their own, even when the machine’s thinking remains mysterious to them. Meanwhile, AI is democratizing access to training, and more female players are climbing the ranks as a result.Today, it is essentially impossible to compete professionally without using AI. Some say the technology has drained the game of its creativity, while others think there is still room for human invention.

In April 2024, a mysterious someone using the online handles “Waifu” and “Judische” began posting death threats on Telegram and Discord channels aimed at a cybersecurity researcher named Allison Nixon.As chief research officer at the cyber investigations firm Unit 221B, Nixon had built a career tracking cybercriminals and helping get them arrested. And although she had taken an interest in the Waifu persona in years past for crimes he boasted about committing, he hadn’t been on her radar for a while when the threats began, because she was tracking other targets. Now Nixon resolved to unmask Waifu/Judische and others responsible for the death threats—and take them down for crimes they admitted to committing.

One more thing One city’s fight to solve its sewage problem with sensorsIn the city of South Bend, Indiana, wastewater from people’s kitchens, sinks, washing machines, and toilets flows through 35 neighborhood sewer lines. On good days, just before each line ends, a vertical throttle pipe diverts the sewage into an interceptor tube, which carries it to a treatment plant where solid pollutants and bacteria are filtered out.As in many American cities, those pipes are combined with storm drains, which can fill rivers and lakes with toxic sludge when heavy rains or melted snow overwhelms them, endangering wildlife and drinking water supplies. But city officials have a plan to make its aging sewers significantly smarter.
