A few months ago, I wrote about people using AI Notetakers in Teams meetings. I’ve spoken several times about the privacy implications of recording Teams meetings, using Copilot, and related practices. One thing I’ve been encouraging people to understand is that, even if you host the meeting and turn off all AI, recording, and transcription…
