 I don't think there's a silver bullet in anything. There's going to be some cost to doing that, and that's going to create some delays, unfortunately, unless there's massive regulation at the global scale, which I think also is hard to imagine. Just to put your business head on again for a moment, to do this at scale, you're going to have to raise a lot more money, presumably. That's right. I mean, hundreds of millions of dollars over time?
