Exposure relates to whether or not the image is too bright or too dark. Regardless of how advanced camera technology gets, there will always be times when the the pictures are not captured with the correct exposure. A correct exposure means the picture is pleasing to the eye, and the subject of the image is identifiable. With the practically unlimited amount of variation in lighting that exists both in nature and artificially, it is impossible for the camera to always get the exposure just right every time. It is easy to settle with a poorly exposed picture, but it will always be disappointing when you realized you missed that special moment because of an error in exposure.
