 This is pretty much the biggest overhaul of search that we've seen in, what, two decades? This new experience will be available to over a billion users by the end of the year. Why did you wait until now? In some ways, we've been evolving it continuously. The good thing about search is people comfortably use it. They take it for granted. We've been answering questions for a while. But with generative AI, we can do it a lot better. We've been testing it for a while, and we now feel it's the right moment to roll it out broadly.
