Legendary Wall Street hedge fund manager Stanley Druckenmiller acknowledged that artificial intelligence assisted him in writing a Wall Street Journal op-ed criticizing his former protégé and current U.S. Treasury Secretary Scott Bessent over expanded buybacks of long-dated Treasuries. Druckenmiller called the intervention a "mistake" and argued that rising Treasury yields reflect high inflation and out-of-control federal debt, not a market failure requiring government action. Crypto venture investor Haseeb Qureshi helped trigger the debate by posting AI-detection screenshots on X and saying the article "obviously" showed signs of AI generation. Druckenmiller said the views were entirely his own, that he has expressed them for more than 15 years, and that he used AI because writing is not his strength. He said he and colleagues at his family office use Anthropic's Claude, OpenAI's ChatGPT, Google's (GOOGL-US) Gemini and Perplexity, comparing AI-assisted writing with using a speechwriter or calculator. The Wall Street Journal opinion editor Paul Gigot defended publishing the piece, saying the key questions were whether it reflected the author's original arguments and whether Druckenmiller had the standing and credibility to make them. The episode underscores the unresolved divide over AI disclosure, contrasting the Journal opinion section's permissive stance with the Financial Times' decision earlier this month to add a disclosure to an op-ed by Harvard professor Ricardo Hausmann after learning he used AI to condense a longer draft, contrary to its code of conduct.
