This is analagous to some of the problems in physics. There are some questions that we can see how to decide, but can't afford to do it now or the tech isn't sufficiently advanced yet. Then there are those where we can see in principle how to decide, but don't have a clue about how we might do it in practice. Finally there are those where we can't see how to decide. It is debated as to whether these fall within the domain of science at all.
