Are AI financial advice tools any good? I tested them with real money for a week

As someone who has spent days running operators on Ascend hardware, I have a professional sensitivity toward things that "look reasonable but are practically uncomputable." This NBER paper used randomized controlled trials to compare AI advice, human financial advisors, and suggestions from the "typical American," testing feedback from over two thousand people. The conclusion is that AI advice performs about as well as human financial advisors. But there are still several layers of VRAM between this and something actually "usable."
