Hype around humanoid robots is reaching fever pitch, driven largely by the idea that the same AI advances behind ChatGPT and Claude could let robots imitate human movement the way chatbots imitate human language. Many researchers are skeptical. They argue that such assumptions minimize the challenges of using an intelligence built on language and images to master the infinite variability of the physical world. They also point out that conflating humanoids with so-called generalist machines is misleading. Across robotics labs, tensions have emerged over whether current forms of AI are all that's needed to perfect all-purpose humanoids or whether an entirely new path is required.
This edition of The Download also highlights climate technology. As sea levels rise and flood risks worsen, Wave Save has developed a portable rubber dam called the Slam Dam. Anyone can unfurl it on the ground along a riverbank or shoreline and pump it full of water until it swells into place. It stands up to 1.3 meters high, shielding nearby property or structures from damage as waters rise. Wave Save is one of MIT Technology Review's 10 Climate Tech Companies to Watch 2026, available exclusively to subscribers.
The newsletter's must-reads include scientists in Austria and China who have built the first nuclear clocks, which could become the world's most precise timekeepers and may help search for dark matter. Three fired OpenAI researchers, meanwhile, want to protect AI reasoning monitoring, warning that AI companies could lose a key safety tool. Samsung has also forecast its highest quarterly profit ever for a tech firm, with projected profits of $80 billion driven by the AI chip boom.
