As many have already said in this thread, both types of research are important and I do not necessarily see one as more important than the other. There will always be a need to solve current societal problems, for this reason research is needed to help further understand these problems so that a solution can be identified. Broader types of research that do not particularly have a definitive understanding as to what the end goal or end product might be are also extremely important. These types of research help our society gain knowledge about many different topics or industries that may not even have current problems, but the ongoing pursuit for this type of information / knowledge could be an integral part in solving future problems. Essentially the point I am trying to make for these broader (future) types of researches is not to wait for a problem to exist before you start looking for a solution. From my personal opinion I would prefer to work on research that would help future generations. I do agree with what many others have said it is very rewarding to see your accomplishments, and have tangible evidence for what your work (research) was able to achieve. I would personally rather be part of something that has the chance to change our society as a whole and have a major impact. Even if it meant only playing a smaller role in making this major impact possible and not receiving any recognition.
