The problem with the Soviet education is the assignment of credit to the inventors. They used to teach that the phone, TV, radio were all invented in USSR. People didn't know any better.
In other words, if most of the US films get the Oscar awards doesn't mean they are the best films out there. If scientists get Nobel prize doesn't mean they are the only greatest. All the awards and prizes are biased.
I really like to see how people ignore something because they got "proper education". That's so debatable. The world is not only US and Europe. There are some other countries and cultures exist too. :-)

The death of Losev by starvation at the siege of Leningrad arguably set semiconductor technology back by a decade or more. Unlike Marconi, Tesla, DeForest, and other prominent poster children of the wireless era, Losev wasn't engaged in a foot race to the patent office with numerous other well-funded competitors. He could have made some incredibly valuable and unique contributions if his work had been better known and supported.
Laser technology, on the other hand, was only "suggested" by the Soviet researchers, not actually implemented. A lot of different people were "suggesting" a lot of different things back then. Charles Townes's biography ("How the Laser Happened") is very much worth reading for anyone who's interested in this stuff.
