Thats an American outlook IMO. Asians are more geeky about "stuff". Just look at the difference in the way technology is used in the US compared to the way it is used in Japan. I do not see Americans using robots in their home anytime soon, for instance. As long as we're getting the know-how, why should we also need to endanger lives?
Robots are very good at doing some things, and very bad at doing other things. So far, robots have proved to be very good, at doing highly repetitive and boring tasks. As their "minds" are incredibly simple, they can do very simple tasks, very fast and cost-efficiently, without variation or mistake, great then for doing welds upon mass-assembled cars cranked out, all the same. Since their task is very simple, such robots only have what is needed to do the task. Only an arm and its tools, not the whole body and mind of androids, like in the movies. Of course, one reason why robots and androids appear so smart in movies, is because they often are played by real human actors. In Star Trek, Data is played by Brent Spiner. So much cheaper to wear some off-color makeup, than to get a robot to do all his actions and stunts. Of course, I noticed when the side of Data's head was opened up, releaving circuits and flashing LEDs, great for movie illusion, as real circuit boards likely would lack the flashing LEDs, Data's head was "too wide," as obviously, that stuff was "added" to the side of his face, for that camera shot, as presumably, the actor wouldn't allow flesh to be subtracted from his face, to make room. Oh, yeah, they use makeup and blend the two together, to try to fake the illusion, that the side of his face/head was "opened." Often, if the camera angle is just right, and they don't show it for too many seconds, the illusion looks fairly real. But then, DVD slow motion and freeze-frame, doesn't exactly help the illusion stay so real looking. And I will back up the DVD, and slow-mo, trying to figure out how they did an effect.
Robots are also good for working in certain hazardous environments, not so friendly for humans to enter, say like outer space. But so far, robots are generally too stupid to do diverse tasks on the ground, where humans can better do them. I can't see paying big money for a robot vacuum cleaner, that wanders around almost like some confused animal. Why? I already have a vaccuum cleaner with a lot more power, that I can push myself, and compete the task in a few minutes. But if those robots were designed more like humans, with arms and legs and hands, so that they could then be programmed to do most any task that humans can, and had far more sophisticated software, I would love to have a robotic household maid, like on The Jetsons cartoon. I don't think they got it quite right on the cartoon though. I don't think such robots would roll around on little wheels. I think robots would "walk" like humans, so that they can navigate our stairs and go where we can go. Because, think about it. Balancing and walking, is among the "simplest" tasks that humans have to do. Babies learn walking rather early on, compared to other tasks. If a robot can't figure out how to "walk," it likely won't learn how to do much anything else either, other than of course, highly repetitive boring tasks. And I do think robots would have to learn the human world, because we wouldn't want to change our world for the robots. Do we even need a car that can drive itself, if the robot can sit in a car like a human, and drive the car the same way as humans do? But given enough time, I think both methods could become possible. Then humans will have to be banned from driving, and our cars will drive for us, because so many people are such terrible drivers. Distracted, not using turn signals, tailgating, too aggressive, too impulsive, too much in a hurry. I think iRobot got it about right. Cars will drive so much faster, and safer, once the computers take over the driving.
BTW, we don't seem to see very many robots in Star Trek. Why is that?
