You mean besides "do a helluva lot of neuroscience"? A lot of our good qualities are subjective, in the most basic sense of that word. We don't even understand their physical basis well enough to predict whether (or which ones) significantly different physical systems will share. If you want to know whether robots can take your job, the question of whether machines can think is exactly as uninteresting as whether submarines can swim (h/t Dijkstra). If you want to know whether you can become a certain kind of robot, that's a whole 'nother story.
