Your AI is emailing my AI—and nobody’s in charge

The central premise is striking: when half of all U.S. workers use AI to write emails and messages, and AI assistants increasingly read and triage incoming messages, a growing portion of workplace communication has no direct human authorship on either end. The Fast Company piece frames this as a leadership challenge — how do managers maintain genuine relationships, cultural accountability, and decision-making clarity when communication defaults to automated on both sides? The piece offers guidance for leading in this environment, though the available text does not detail specific recommendations. The broader trend is real and consequential. AI email tools embedded in Outlook, Gmail, and enterprise platforms are becoming defaults, not opt-ins. The signal-to-noise ratio in professional communication is changing, and the question of who is accountable for a message's content becomes murky when the author is a model. For AI practitioners, this is the agentic workplace arriving in its most mundane but widespread form — automated professional communication — and it is already mainstream without most organizations having explicit policies.
