I think that pursuing very ambitious technology itself brings a reward. It advances the skills and capabilities of our teams. In many cases, we can actually develop potentially patentable technologies in the course of doing that. Whether it's ultimately taken up and put into use is not necessarily the sole way you define success. I actually think there's a lot that's gained in the learning process of attempting things that are very challenging. In fact, most things that are very challenging can have a high failure rate as a consequence of being really complex stuff that we're trying to do. Yes, there's a benefit.
