 global warming, which is kind of a long topic. The other one I wanted to point out, though, is that I actually have a background in material science, and one thing that I've worked on for many years was optical computing, and that's actually coming. Now, if that happens in a large-scale way, you'll see this transition in the next maybe five to seven years, which is going to reduce the actual energy footprint of things like data centers and certainly for large-scale computing facilities. I was kind of wondering if you had any comments on either of those. Yeah, well, the second one first, I really can't comment on optical computing. I don't know about that.
