Hi, Irma. So on product development, a couple of important, I think, clarifications, yes, it continues to be the most significant line in terms of deleveraging. I think on super solid top line, when we look at margin expansion, we've been able to generate incremental margin across most of our cost lines. The two that haven't on a year-on-year basis are certain sales taxes, primarily in Brazil, and then 220 basis points from product development. Bear in mind that the rate of incremental hiring has come down from about 4,000 engineers to 2,000. And so a significant portion of those 220 basis points are a consequence of the annual realisation of all the engineers that we hired last year, and not a continued acceleration in rate of engineers hirings. So for next year, we should begin to see a slowdown in the level of deleveraging from product development, unless we significantly ramp up hirings, again, which is currently not on the plans. In terms of areas of of investment, it really is across the board. We see our product and our technology as a competitive advantage. And those engineers are really split across the multiple different products and services that we are either building out or improving constantly. So they're fairly evenly distributed among the existing businesses you're well aware of. In terms of AI, I think as most companies, we do see some very relevant, short to midterm positive impact in terms of engineering productivity. And we are also increasing the amount of work being done on what elements of the consumer facing experiences we can deploy AI on. I think the focus right now is on some of the more obvious use cases, improving and streamlining customer service and interactions with reps, improving workflows for reps, through AI assisted workflow tools, and then deploying AI to help a better search and discovery in terms of better finding products on our website, and better understanding specific -- specifications of products, where existing LLM are quite efficient. And then beyond that, I think there's a lot of work going on. And we hope to come up with other innovative forms of AI that we can place into the consumer facing experience, but the ones I just mentioned are the ones that we're currently working on the most.
