I couldn't comment on whether I agree on that particular statement or not. I apologize. It's not something I've studied long enough, but I can speak to the future of in situ. Part of the technology development either Suncor is doing on our own or through COSIA, Canada's Oil Sands Innovation Alliance.... We believe there is step-change technology—sorry, that was an engineering term—through in situ that is going to revolutionize the industry. We think that takes the current paradigm of natural gas consumption, which is what produces the greenhouse gases, and shifts it, maybe potentially reduces it in half, and so changes that whole dynamic and makes it that 12% or 13% rate of return. That changes the conversation.
That's the approach we're taking. Our next generation of in situ plants looking past 2022 or 2023 will, I think, look quite different from today.
