This article from MIT Technology Review covers two distinct tech topics. The first explores the ‘Vitalism’ movement, a growing trend where individuals use technology to meticulously track and optimize their biological data, such as heart rate and sleep, in pursuit of enhanced health and longevity. The second, more prominent section examines a critical privacy issue emerging in artificial intelligence: the development of AI with persistent memory. Unlike standard models that process queries in isolation, these new systems can retain personal details from previous conversations, creating a detailed, ongoing profile of a user. This capability raises significant concerns about data security, user consent, and the potential for sensitive information to be exposed or misused. The piece highlights the need for robust safeguards and transparent policies as this technology evolves.
