I believe it'll be somewhere within the field of healthcare. With new illnesses and viruses roaming around each day, the bar is raised higher and higher by the second for researchers and physicians. An improvement in technology will be critical in the field of healthcare. It always has been, and I don't see that changing anytime soon.
Though, as it always has been, the advancement of technology in healthcare is dependent upon the advancement of other technologies. Whether it be communication, the various sciences, transportation, medicine, and the like. Technological advancements play off of each other in such a consistent manner, it's mind-blowing.
