Why did cuneiform symbols change as time passed?

Cuneiform symbols evolved over time due to several factors, including changes in language, the need for more efficient writing, and the influence of different cultures and regions that adopted the script. As societies advanced, the symbols became more abstract and simplified to facilitate quicker writing and to accommodate new vocabulary and administrative needs. Additionally, the adaptation of cuneiform by various civilizations led to modifications in the script to suit local languages and contexts.
