There are two factors related to this question. 1. Is the research question topical, of importance, not previously investigated, shedding light on a new angle to a problem and hence relevant to society, researchers & politicians. 2. Who is funding the project? is there funding? is there adequate funding? Some examples are; Technology information overload, information overload and technology integration, data privacy problems, confidentiality, systems integration, functionality of systems, timelines, costs, artificial intelligence. These are all topical issues - there maybe factors to explore/ investigate. So probably an area where there are opportunities for jobs/ research. I think also in the future the jobs in this area will continue to increase / expand. Another example which desperately needs investigation and alteration is the church, lack of science and religiosity. A very urgent issue that must be addressed, for rules, laws & policies regarding their outdated practices & teachings of prayer for this, that & the other. A very difficult & challenging project in that they are set in concrete in their antiquated ways of working & no one seems to care or want to change them to integrate science with religion. A very urgent & topical issue that is in fact causing many people/countries much distress & upset, but if you do a project in that area, it will be important, vital & necessary, but I doubt it will get you a job. Noone wants to fund research like that, & that probably won't give you a lot of scope to move in the future unfortunately. Just two examples to ponder.
