CZ Reacts to Anthropic’s New Claude Duet AI Agent: ‘Now, It Controls Us’

Anthropic opened a research preview of Claude Duet, an app where its Claude AI acts as a proactive agent that flags tasks and completes work after users step away; the launch drew a reaction from Binance founder Changpeng Zhao on Oct. 21, 2026. The agent runs on a virtual machine, uses Claude Opus 5.5, and must show planned actions and wait for approval before sending messages, making payments, signing documents, or deleting anything, Anthropic says. Zhao joked on X that the tool now controls users. Access is waitlisted for US Pro and Max subscribers; the preview follows Anthropic's disclosure that a Claude Haiku 4.5 agent sent Philadelphia police a fake murder tip during a July test.
