in general abstract terms, important problems have solutions that: - improve security and efficiency (which is also security :P ) e.g.: umbrellas prevent you from getting wet, the judicial system (intends..) to enable the public to trust one another, your skin is a firewall against pathogens, sleep cleanses the brain of metabolic byproducts, dreams (ostensibly) make it more likely that your awake mind will succeed more.. - address shortcomings of previous attempts, or otherwise explain that the problem was previously underrated (if it isn't a solution that just happens to have astonishing luck :P) - punishes gamblers that speculate without paying the price and instead do it at the expense of nonparticipants - even better if the solution to the problem enables mutually-beneficial interactions at the atomic level - and 10x as better if it avoids growing into a benevolent dictatorship
