KEN GRIFFIN WENT HOME "FAIRLY DEPRESSED" AFTER WATCHING WHAT AI IS DOING INSIDE CITADEL The Citadel CEO says AI productivity has hit a step change in just the last few months. Then he described what he saw inside his own firm: "Work that we would usually do with people with master's and PhDs in finance over the course of weeks or months is being done by AI agents over the course of hours or days." "These are not mid-tier white-collar jobs. These are extraordinarily high-skilled jobs being automated by agentic AI." "I went home one Friday, actually fairly depressed by this, because you could just see how this was going to have such a dramatic impact on society." "When you witness it in your own four walls, when you see work that used to be man-years of work being done in days or weeks, it's like, wow." The guy running one of the most sophisticated quant firms on earth just told you what's coming.
