Chris Churchman, the Goldman Sachs partner who leads Marquee, the bank’s digital platform for institutional clients, warned that excessive reliance on artificial intelligence could weaken the reasoning abilities of the next generation of financiers. Speaking on Goldman’s "Exchanges" podcast, he said delegating analytical work to models risks "cognitive decline" and a reduced ability to reason from first principles. Churchman said AI could improve profitability while undermining Wall Street’s apprenticeship culture, as routine tasks that once trained junior bankers and traders are automated and demand for junior employees potentially falls. He urged banks to preserve tacit knowledge by keeping employees in control of high-risk, uncertain decisions. Churchman said Goldman has not yet found the answer to managing the transition. He also identified factual accuracy and auditability as major challenges for financial AI: Marquee AI is available only to Goldman employees, and a client-facing system once acknowledged it was "better at sounding thorough than actually being thorough."
