Should tired workers be banned from using Microsoft Copilot on Friday afternoons? "AI fatigue" could lead to lazy mistakes

Mid adult businessman covers his face with his hands while seated at his desk, expressing a moment of stress or contemplation in a startup office paired with the Microsoft Copilot AI logo.

During a talk about “Mitigating the Top 5 Microsoft 365 Copilot Security Risks” at Gartner’s Security & Risk Management Summit in Sydney on Tuesday, analyst Dennis Xu jokingly suggested banning the use of Microsoft Copilot on Friday afternoons.

He noted that by the end of the week, many users might be too lazy to double‑check whether the chatbot’s outputs are offensive, which raised his concern (via The Register).
