signal messaging

The signal messaging tag covers privacy and security concerns surrounding modern AI assistants and their expanding access to personal data. Current coverage highlights a warning from Signal President Meredith Whittaker that chatbots such as ChatGPT, Claude, and Microsoft Copilot should not be treated as friends, confidants, or private interlocutors. The discussion focuses on the shift from simple text interfaces to agents with memory, visual access, payment authority, and connections to other digital services. It also examines how these capabilities could weaken the separation between secure apps, browsers, calendars, and payment systems, broadening the privacy debate beyond prompt retention and model training.
