 larger picture of the economics of global warming, which is kind of a long topic. Everyone would point out, though, that I should factor in material science and what they've worked on for many years with optical computing, and that's actually coming. Now, if that happens in a large-scale way, you'll see this transition 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 wondering if you had any comments on either of those.
