Microsoft Copilot is why most professionals still think AI is overhyped

Microsoft has spent the past two years turning its 450-million-seat productivity monopoly into the most aggressive AI distribution push in enterprise software history. $37.5bn in quarterly infrastructure spending. Copilot buttons threaded through every ribbon in Office. Bundling across Windows, Edge, and Teams, and a full leadership reorganization to concentrate the effort under Satya Nadella's personal control. The scale of the bet is unprecedented, the distribution is unrivaled, and the product now sits on the desks of virtually every knowledge worker in the Fortune 500. Which makes one sentence, tucked quietly into Microsoft's latest terms of use, rather harder to explain.

Copilot is for entertainment purposes only. The line, tucked in bold capitals under Microsoft's consumer terms of use and updated quietly last October, surfaced in April when someone finally read it. It landed at an awkward moment: after two years of marketing, $37.5bn of quarterly AI infrastructure spending, and a 450m-seat distribution monopoly pushing behind it, Microsoft's flagship AI product is the tool most professionals have actually tried — and most professionals are not impressed.

The numbers behind that impression are brutal. Microsoft has roughly 15m paid Microsoft 365 Copilot seats against 450m commercial M365 subscribers — a conversion rate of 3.3%, which The Register described as "an awkward figure that landed alongside Microsoft's AI splurge and its insistence that the payoff is coming.” Sensor Tower data reported by CNBC put Copilot at roughly six million daily active users in February 2026; ChatGPT had 440 million, and Gemini had 82 million. Gemini passed Copilot's paid-subscriber share back in late November, and Copilot's U.S. paid-subscriber share fell from 18.8% in July 2025 to 11.5% in January — a 39% contraction in six months. Recon Analytics, which tracks paying AI users, put Copilot's accuracy Net Promoter Score at -3.5 last July; by September it had cratered to -24.1, recovering only partially to -19.8 in January. Of users who had quit the product, 44.2% cited distrust of answers as the reason.
