I just wanted to talk a wee bit about how the incentives are set up. So in a purely voluntary agreement, you can imagine that the incentive—not through any malicious intent—is to go slowly, right? If you're on to a winning wicket, why would you want to change? In a voluntary agreement, there's no particular reason to achieve any particular outcome by any time, right? You can just continue doing R & D and so on, because there is no point where you need to actually change behaviour, right, or to change any systems.
