Why can’t vector graphics produce photographic quality images?

Straight lines, circles, ellipses, and arcs are the main components of vector art. Therefore, until recently, vector graphics were used to create drawings, diagrams, graphs, as well as to create technical illustrations. With the development of computer technology, the situation has changed somewhat: today’s vector images are close to realistic in quality. However, vector graphics do not provide photographic quality images. photography is a mosaic with a very complex distribution of colors and brightness of pixels, and representing such a mosaic as a set of vector primitives is a rather difficult task.
