Ada Lovelace was a very important person for the future of technology building. She first thought of the idea to expand computers to more than calculation, like music, entertainment, and important scientific work. The notes that she took while translating papers on the Analytical Engine were later considered the first computer programming.
This is an enormous achievement for the advancement of technology. Charles Babbage was only planning to have the computer do translating and calculating mechanically, while Ada wanted to have the computer be used for science studies and music. This relates to the theme of change because change is necessary for growth. And change and growth is exactly what Ada Lovelace brought forward with her unique and different ideas.
