EY Did It Last Month, KPMG Did It This Month — Big Four Auditors Now on a Hallucination Rota

Last month EY's loyalty-rewards paper had invented footnotes. This month KPMG pulled an AI report after the detector GPTZero flagged hallucinations. Deloitte's apology is presumably already in the printer queue.

Last month EY — one of the four giant accounting firms — quietly pulled a report on supermarket loyalty schemes because the footnotes pointed at studies that did not exist. This month KPMG, another of the four, withdrew its agentic-AI paper after GPTZero, a detector that scores text for machine authorship, flagged the prose as synthetic.

A GPU running an 8-billion-parameter model at inference draws roughly 700 watt-hours per thousand pages of slop; across a Big Four rotation that's 2.8 kilowatt-hours of cooling water boiled off to fabricate citations a graduate could have written sober. I did the arithmetic.

Deloitte's apology is presumably drafted, awaiting only the date. PwC takes December.

Meanwhile Geoffrey at EY still prints every deck single-sided.
