with the rise of flying platforms and ed printed flight suits self steering bullets/mini missles with object recognition and integrated cameras could be a thing soon. also self stabalizing sniper rifles kinda like helicopter chase cams.
arduino SOD might be able to perform the task in a bullet the size of your pinky finger. alot of room for innovation still stems from iron man movie and zorn industrys in the movie fifth element (1997).
