This article from MIT Technology Review explores two distinct technological trends. First, it examines the ‘Vitalism’ movement, a growing cultural and technological shift focused on using data from wearables and other sensors to optimize personal health, longevity, and physical performance. The piece looks at the philosophy driving this movement and its implications. Second, the article addresses a critical issue in artificial intelligence: the development of AI systems with persistent memory. While this feature allows for more personalized and helpful interactions, it raises significant privacy concerns, as these AI models could retain sensitive personal information indefinitely, creating new risks for data security and user consent. The discussion highlights the tension between technological advancement and individual privacy rights.
