The other one I wanted to point out, though, is that I checked back on material science, and one thing that worked out 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 wondering if you had any comments on either of those.
