Computer Science and computing was largely developed due to military initiatives and research funded by the public. The US and UK governments invested heavily into this realm during their wartime efforts in the 1900s. Notable examples include the foundations of our internet (as ARPANET) via the US military.
In the global context that both of these nations exist in, their technological advantages were used across their respective empires and military excursions. Furthermore, both nations have huge influences across the tech, finance and IT sectors as a result of their historic establishment in this world. We routinely see A.I., surveillance, and technological devices of war impact those across the globe with profit incentive in mind. This is where Colonialism historically and contemporarily links into Computer Science.
