On the one hand, big companies such as Amazon and Google have used these tools to build vast commercial empires based in part on predicting the wants and needs of the people who use them (Gatopoulos, Aljazeera, 2021). On the other hand, the development of AI in the military originated a few decades before and has been more intense and challenging.
