Future of PMR

Current Intern, so take with a grain of salt, but now that I'm starting my career, I'm beginning to look ahead and figure out what exactly the future for PMR holds whether that means inpatient or subspecialty wise. I am pretty open minded on what I want to do but I am pretty set on fellowship (at the moment) and I am interested in sports med and pain. I have been hearing for some attendings that the future of PMR is probably going to be in cancer med as that is a HOT field and regenerative med (which I think is really cool as well). I know stuff is liable to change in the upcoming years and I am early to make decisions but I would really like to have a good idea when looking at fellowships as well as going into practice.
