Why does the power of artistic expression fade over time?

The power of artistic expression can fade over time due to shifts in cultural values, societal norms, and audience perceptions. As contexts change, the themes and messages that once resonated may lose their relevance or impact. Additionally, the saturation of certain artistic forms or styles can lead to desensitization, diminishing their emotional or intellectual power. Over time, new artistic movements often emerge, reshaping the landscape and overshadowing earlier expressions.
