"Mathematics is the cheapest science. Unlike physics or chemistry, it does not require any expensive equipment. All one needs for mathematics is a pencil and paper."

The inner sort of consumer identity got the best of people. And everybody just wants things for free. And that's created this strange kind of cheapness to everything, where everything becomes throwaway. And people, I think, have started to undervalue things, maybe because there's too much, maybe because it's too easy to make, but I think mostly just because, somehow, that's the pattern that got set. And I think that's regrettable.
