what the fuck! Silicon Valley tycoon Peter Thiel reveals the terrifying moment when PayPal was on the brink of bankruptcy. In the early days, PayPal faced an extremely serious fraud crisis, with funds being crazily looted and anti fraud executives crying and falling asleep every night in despair. Facing millions of transactions with just twenty investigators is like finding a needle in a haystack. In order to survive, the company hired a group of top mathematicians and computer scientists to develop an AGI system to catch all the bad guys. But they soon realized a cruel reality that AGI would take at least ten to thirty years to achieve, while PayPal would burn out all its money and completely go bankrupt within twelve months. In the face of life and death, pure manual investigation or pure computer automation are both dead ends. The ultimate solution to save the entire company is to thoroughly understand the perfect division of labor in human-machine collaboration. Let computers screen massive amounts of transaction data on a large scale, filter out suspicious targets, and then hand them over to humans for complex qualitative investigations. This hybrid mode has unleashed tremendous power. Thiel explicitly pointed out that even today, this collaborative paradigm that allows machines to leverage their computing power advantages and humans to leverage their cognitive advantages is still severely underestimated by the entire AI research community! Facing the wave of AI, finding the right division of labor between humans and machines is the most core wealth code at present!
