The sourdough isn't special just because of its sour taste
, it's special because its often associated with the simple things in life, remembering how not everything has to be complicated and industrial, some people might wonder why make a bread that takes more than a week to leaven, when there are agents available that leaven the bread under a day or why make bread at all when its available in every supermarket. It's natural, it shows us that we don't have to rush everything, nature doesn't rush anything either and everything gets done.
