Hard problems are hard because they involve humans. For some reason, the author is confused between the two. Complicated or advanced is not the same as hard. Anyway, impact is more important than complexity, and not quite as obvious. A hard problem is climate change, or managing energy market, or figuring new recycling chemistry. Perhaps providing specific medical care in safe manner, or reducing health problems. Providing food or housingfor 10 billion people, that's a hard problem. Getting everyone free education of good quality is a hard problem. Electronic voting is a hard problem. Hard problems are generally ignored. They do not have obviously actionable solutions. Complicated problems tend to have many solutions or partial solutions. Additionally it's easy to create a hard problem with an unnecessary solution to a non-problem, see that Wave thing he mentions. (There are many other workable and cheap loan solutions.) Or fool yourself that you're actually solving any real problem. That typically happens if you define goal without consulting the subjects. (This Wave thing smells of it.)
