While the US could use (homebuilt) computers to solve engineering issues, the Russians had to resort to manual calculations. The eastern block always lagged behind in terms of computing.

All the time.
Post 2016 the messaging from most commonwealth countries (UK, Canada, Australia) seemed to be that they were going to be the ones bennefiting from a brain drain of americans leaving the country. Canada was supposed to become an "AI Superpower" and Universities in the UK were supposed to be where innovation was going to happen next due to the perceived hostility of the United States to foreing talent. I recall someone pitching the "Silicon Roundabout" and that Cambridge and Oxford were going to be the new Stanford and MIT.
It's interesting, in retrospective, to see how wrong these predictions were.
