Deepak, it's Tony. Yes, I can maybe start on both questions, and Ravi, feel free to add. Yes, look, on the first question of where are we spending, we're primarily investing in 3 areas and kind of the second part of your question kind of feeds into the first part. So the first major area is building a new global tech platform. And so this is an effort that's been underway for a couple of years now, but it's coming to a head where we're actually making the majority of those investments in 2026. And what is its purpose? Well, there are several reasons of what we're trying to accomplish. The first thing, what we're trying to accomplish, is we're trying to build a single global tech stack, where when we launched one experiment, the experiments that actually make it to our customers can be shipped at the same time across all of our markets and all of our audiences. Today, that doesn't work that way as we have 3 companies at DoorDash on the restaurant delivery, our marketplace front with Deliveroo, Wolt and DoorDash. In the new world, we'll actually be able to have 1 feature go live to all audiences; whereas today, that 1 feature would get to have -- would pretty much have to get shipped 3 times, which is very inefficient in how we do that. Another goal of the tech platform is to, like you said, in your setup, to make it AI native. And so there will be lots of tooling there where -- I may have mentioned this in the previous call before, where if we were starting a company over again today, I think we would write software pretty differently from how we used to do it. And so there's a lot of work in order to architect how we set up the architecture, so we can manage both agent workflows as well as how you would deploy software, test software, write software, what the role of the engineer is in that new paradigm. All of that is getting constructed as part of this work. Yes, and I do actually think that, at the tail end of this work, you'll see, on a go-forward basis, not only will we ship faster and ship improvements across the board globally. We'll actually be more efficient, and we'll have freed up engineering capacity to do a lot more work. And so that will allow us to not only have a better cost structure but really just be able to do a better job in solving the next problem for customers. So the first area of spend is in building our tech platform. The second area is investing in new products. And so we announced probably, well, several launches in our dashboard product events, which happened at the end of September. And we're really excited about them. A lot of times, when you're building a company, what you're really doing is you're starting with lots of experiments. Some of those experiments make it into products. Some of those products then can be graduated into commercialization where you're trying to test whether or not you have a good business. And then some of those candidates then ultimately yield big businesses that generate the cash flows to allow you to invest in the next set of products and experiments. And I think we're really fortunate at DoorDash in a couple of ways. One, in the area of local commerce, there's just a lot of different problems. And one is -- and the other way in which we're lucky is that a lot of the experiments, many of these have been running for years, are now coming ready for more investments. And so we're very excited to be investing behind them. We announced, for example, a lot of work on in-store and building several products there with going out, reservations and our CRM platform behind SevenRooms. We talked about DoorDash Dot, which is the customized, purpose-built for delivery autonomous vehicle, the first in the world to drive on the road, sidewalk and bike lanes in order to make that happen. We talked about DashMart Fulfillment Services, where we're creating an ability for any retailer to offer same hour or same-day delivery with near-perfect accuracy. So these are some examples of the new products that we're talking about. But if you think about it in each case, we're running the business exactly as we always have, where the goal is we want to make sure that we always can solve the most number of problems for our customers in the highest quality ways, and we manage our projects carefully to milestones. And as they deliver upon each milestone, we grow them into businesses, and we continue to invest behind them. I think our track record in investing in the areas that we currently have operating, whether it's U.S. restaurants, U.S. new verticals, the international business, our commerce platform, our ads business, have suggested that we've had some success in repeating this playbook, and we're doing this now for future growth.
