Why does software tend to increase in complexity as it evolves?

Software tends to increase in complexity as it evolves due to the accumulation of features and functionalities intended to meet user demands and market changes. As developers add new capabilities, they often need to maintain backward compatibility, leading to additional layers of code and dependencies. Moreover, the integration of various technologies and frameworks can introduce new complexities, making the software harder to understand and manage. Finally, as teams grow and evolve, differing coding styles and practices can further contribute to the overall complexity.
