Once upon a time there was a magic mirror. This mirror was able to know who the most beautiful woman was in the world.
The evil queen, stepmother of Snow White, used to admire herself in the mirror, asking, “Mirror, mirror on the wall, who is the fairest of them all?”
After the evil queen died, the mirror served many mistresses over the centuries who asked the same question. So for centuries, the magic mirror only needed to answer 1 question.
Fast forward to the modern era, the magic mirror finds itself replaced by the internet because the internet can answer the same question and many more.
