At least the backscatter x-ray machines are gone, now replaced entirely in the US with millimeter-wave scanners. Personally, I don't care if somebody's looking at my body on a computer monitor. However, I do care if I'm being exposed to extra ionizing radiation for no good reason. Which is why I always opted out of the x-ray machines, but don't really mind going through millimeter-wave ones. (Obviously, other folks will feel very different about this. If your concern is privacy, the millimeter-wave machines aren't much of an improvement -- though I do believe most of the human elements of the system have been replaced with image recognition on newer versions.)
