<p>ABT, you are correct (to a point) about engineers, in practice most of them do not use pure math or develop new mathematics, they plug-and-chug. But you are mistaken if you think engineers don’t <em>learn</em> pure math at the undergraduate level. Many engineers take the same rigorous, proof-based classes that math majors take, especially electrical and computer engineers (I guess it depends on the school). And many working engineers on the cutting edge of R&D (either in the university/RI or for commerce) do math snob brand math.</p>
<p>But, to one degree or another, your attitude and the attitude of people you’ve alluded to smacks of fanboyism, and I mean that in the nicest way. Fanboys hate it when something they like becomes popular, and they must move on to evermore obscure and esoteric areas of their interest. Let me use examples of fanboyism in other areas to illuminate:</p>
<p>Hong Kong action film fanboy: “Man, Jackie Chan is such a sellout these days. And that Crouching Tiger, Hidden Dragon sucks! I hate hearing about it! I’m going to go watch some ultra-obscure movie that most people in Hong Kong have never heard of.”</p>
<p>Foreign film fanboy: “Amelie, Chocolat, what tools! And it seems like everybody these days has heard of Fellini and Bergman! I need to start watching Gaspard Noe movies, that’s REAL foreign film.”</p>
<p>Video game fanboy: “Everybody thinks Guitar Hero and Wii Fit are great videogames. Bah! Tim Schafer, Warren Spector, and Valve are the only good American developers left.”</p>
<p>Anime fanboy: “I can’t believe people like Akira and Ghost in the Shell. That’s not real anime! Grodus Chronicles, now <em>that’s</em> real anime!”</p>
<p>I could do these forever, they’re so much fun. Some of them are me (video game snob) and some of them I hate. But I think I made my point. Would you tell Newton that he wasn’t a real mathematician?</p>
<p>Again, I mean this all in the nicest way, I’m not flaming.</p>
