I would prefer to create research that helps current generations. I believe that technologies and information builds upon itself so if you help current generations, you are helping future generations as well. For example, if one creates a cure with immunology to some form of cancer (actually happened), this opens the door to use immunology to cure other types of cancer. They might not know everything at the moment to cure these other types of cancer but the information that you output gives them the basis for someone to one day go back to that problem. In the future, they might actually be able to solve the problem with the information you outputted combined with other people’s information as well.
