Well I can say you this about Soviet technology and their powers. Soviet union never did anything for technology, they had loads of engineers and scientests, but their sole purpose was to copy tech from the west, they never did anything creative, their sole purpose was to steal or get their hands on something and then try to copy it. When I say all I mean all, everything, I have stories how they probed in institutes VHS and such devices
And that's a true story, I know loads of people who were scientists or engineers in the soviet union, and were working throughout all of soviet union in St petersburg, Mascow and the like.
My uncle worked in some engineering factory that made things for the military air aviation (his unoficial job was to screw with faulty electronics so that it would pass the test. There were job titles as called magicians, they were responsible for doing similar things with military sealed tech, so that the faulty ones would not mess up the batch and the batc would not need to be redone, but end up in the end product), and the quality, work ethics and how things were done there would be laughable to any westerner who knows how a factory should work. The whole chain supply of parts and products was faulty and messed up, that's how shitty the industry was. Even you wanted to make an airplane with everything working it was not possible. And that goes for most industries.
There were loads of smart people, but the enviroment wasn't good for them in science field, because from the top no one wanted to invent or thought it was too hard maybe.
The soviet union had some good with it, but saying it was almost an utopia or even more to brag about soviet technological achievements is just ridiculous.
