 Real computer science is a field that is about both capabilities and limitations. But it is a field where you're constantly stepping back and saying, can I abstract the entire class of techniques that I've just been trying on this problem? And can I prove that nothing of that sort can possibly work? I mean, that's the nature of the business. And because we're thinking about things that are as powerful as sort of general models of computation, often those tools do let you formalize things like that, like the class of all possible techniques that correspond to polynomial time algorithms in this or that way. The sociology of the field, I mean, I think most people are pretty nice. I mean, if I didn't think that, I would be in a different field, probably, but there's lots of competition, as there is in every area of academia that I'm familiar with. Or there are more people than available grants or available slots and so forth. Quantum computing is in a funny situation because it struggled for 20 years. Quantum computing people struggled because CS department said, no, this is really physics. Physics department said, no, this is really CS. Everyone said, well, maybe it's all going to go away next year. And so it was very challenging to make the case for quantum computing. Now the situation is the complete opposite. And now every department that I know of is like trying to hire quantum computing people and who knows how long that's going to last. So you can go through cycles of bubbles that expand and then pop, but I don't know. I feel like I was doing this before it was so cool. And I like to think I'll keep doing it even if it stops being so cool. In fact, I might have more time for research if it stops being so cool. OK, well, let's thank Scott again.
