 While the reservations expressed in this section may seem pessimistic, they are not, as these observations are serving to move us forward. Much exciting and useful work is being done and remains to be done on the mass/count distinction, as mentioned below, and linguistically-guided metaphysicians will have a role to play in this inter-disciplinary work. It may just be that metaphysicians will have to become more nuanced in their appreciation of mass vs. count, as there will likely become ever more fine-grained distinctions and qualifications to  consider.[24]
