Signal's Meredith Whittaker wants you to remember that AI chatbots 'are not your friends'

What happened

Signal president Meredith Whittaker, in a Bloomberg interview followed up by TechCrunch, rejected the standard marketing line on AI chatbots. She was responding specifically to Microsoft pitches about Copilot handling a user's entire Christmas shopping.

Context and impact

Signal is Silicon Valley's loudest privacy voice and Whittaker among the most-quoted critics of agentic AI. The interview lands the same week Cloudflare opened up temporary accounts for agents – the conversation is shifting toward how much access an agent should actually have to user data.

Details

• 'These are not your friends. These are not sentient interlocutors.'
• Whittaker uses AI 'to format a document here and there', not to think.
• The criticism targets Mustafa Suleyman's (Microsoft AI) vision of an assistant that eavesdrops on family chats.
• It dovetails with Signal's broader 'pervasive access' warning about agentic systems.
