The eternal dichotomy between application and theory! Engineers smugly smirk when their inventions go unused—"hahaha nobody applies your invention"—while mathematicians sob uncontrollably at the same fate. But flip the script with pure mathematicians, and you'll find they're playing 4D chess. One says "Nobody will apply your theorem ever" while the other responds "I hope so" with galaxy-brain energy.
Pure mathematicians secretly want their work to remain theoretical forever—the moment someone finds a practical application, some government agency will classify it and they'll never see their beautiful equations again. Nothing ruins a mathematician's day like learning their abstract number theory just became the foundation of modern cryptography!
