Right, but still, after Stalin's death, USSR had a renaissance of sorts - art, science, tech, quality of life improvements across the board. Still not enough to win the Cold War - was likely impossible - but enough to maintain for some time the lead in some areas and be not terribly outpaced in most others.

One of the points of the article, I believe, is to remind that USSR had their own achievements.
