On a macro scale, those kinds of questions have given rise to a lot of the social progress we've experienced in the last century.

In the future, you'd expect a mature theory of mind to give direction to psychologists or neuroscientists. A rough analogy would be the way theoretical physicists interact with experimental physicists and chemists. It's difficult to create the experiment or speculate about a reaction without a point to jump from. In the same way, a psychologist looks to philosophy to ask "what are the most important questions to people, and how might that reflect in how they behave?"
