 Wow, that's a really good question and I think there's going to be a lot of changes in the next five to ten years. What we see today is not going to be recognizable in five to ten years. It's very important that we use a lot more technology. I think technology and even AI is going to have such an important role in the next five to ten years. When we think about just the sustainability of post, we've been challenged quite a lot over the last few decades and we've been trying to figure out what's that future and that future is constantly evolving and I think in the next five to ten years, especially with all of these new technologies, we are going to see post changing dramatically. The issue is are we ready for that change and I think UPU conferences like this and just the UPU in general is going to be really, really, really central to us figuring out how we move with all of this new technology and remain sustainable. And even when we think about the sustainable development goals and we talk about climate and how we are protecting climate as postal entities, it's going to be so important that we use a lot of these emerging technologies to assist us in moving forward in that goal of sustainability and still being relevant for our people all over the world.
