Well, that is what mathematicians do, which is why I said "interesting" problems. I mean, I can think of several problems, like "classify projective modules over rings of global dimension 4 that have no zero divisors".

Even popular problems in Langlands like "explicitly find a trace formula for theta groups" will appeal to the fifteen people in the world that can understand what I'm even talking about.
