If Chatgpt replaces Google search then it will be effectively signing it's own death warrant.
ML models like chatGPT rely on the open web for training data, particularly for information about recent events. But models like chatGPT are horrible about linking to their sources. That means that sources that rely on ad revenue or even donations to exist will effectively disappear as chatGPT steals all of the traffic. With no cash flow, the sites with current data disappear. With no new training data, chatGPT stagnates.
ChatGPT is basically a parasite on the free and open web - taking content but not giving back.
chatgpt has good chance to kill google search -> kill google.
