London is installing permanent live facial recognition cameras on Oxford Street by Christmas. Half a million shoppers a day will have their faces scanned and compared against police watchlists. The government ran a public consultation on a proper legal framework for the technology that closed in February and still hasn't published a response, but the cameras are going up anyway. Building the surveillance infrastructure first and sorting out the rules later. https://www.independent.co.uk/news/uk/home-news/facial-recognition-cameras-oxford-street-metropolitan-police-b3072030.html

Anthropic used Claude to formally verify security properties in over 100 real-world open-source software libraries at the assembly code level. "Formal software verification could provide this guarantee, but it has historically required years of expert effort, making it impractical for most real-world projects. LLMs can now produce formal proofs at large scale, enabling new software development workflows that include proven security guarantees." Claude also discovered bugs that had eluded detection for years despite trillions of test runs.

Marc Andreessen on the generational divide in how people receive new technology: "If you're below the age of 15, it's just the natural way the world works. If you're between 15 to 35, it's new, exciting, and you might be able to make a career out of it. If you're above 35, it's unholy and evil, and will surely overturn all existing structures and destroy society." "I think 18-year-olds right now, it's prime time to grab these new capabilities and run with them."
