 And that's where we're getting to with this subject now. And I think one of the reasons we're getting there is science. And in particular, I'm talking about the James Webb space telescope, for example, and also the square kilometer array radio telescope, construction of which is now underway. These tools are, I think, going to open a window on a world that has previously been closed to us. And the point where, for example, with James Webb, a lot of scientists, a lot of NASA scientists, for example, doing astrobiology, now talk about not just biosignatures, but technosignatures.
