Slightly off topi, but I think its worth pointing out, as I see these types of threads somewhat often, that a surviving USSR which relies on computers to maximize its efficiency of production will quickly and increasingly ideologically be a Marxist technocracy, as opposed to Marxist communism.
Could you explore what you mean by "communism" and "technocracy" here at length?
I'm assuming you mean by "communism" what people describe as "actually existing socialism" or "the Soviet style socities". I'm assuming you don't mean Marx's own higher stage of socialism, or a classless society. You need to explore this at length because my reading of "actually existing socialism" follows Djilas' new class thesis or the variety of nomenklatura studies. If you follow a degenerated/deformed workers state hypothesis with a bureaucratic caste; or a state capitalist thesis, then you have a very different view of what "actually existing socialism" was to me. We can't simply assume we both mean the same thing by "actually existing socialism," so it needs exploration.
Similarly with technocracy. I assume you don't mean the specific social formation advocated by the utopian technocratic societies in the 1930s. I assume that you broadly mean a social formation where the elite is primarily selected on a technical basis. Given that the three major views on what actually existing socialism was view the ruling stratum of society as being determined by their economic relation to production or social control, whereas technical selection isn't determined by this depth of economic relationship, you need to explore this further.
If you just mean that the nomenklatura will self-select based on cybernetic management abilities rather than bureaucratic human management abilities… this is a kind of truism, and doesn't cover the deep internecine warfare within the Soviet Union that would accompany a change in the manner of elite selection.
(More interestingly, are cybernetic managers inherently more or less democratic than fordist managers? The answer from the West in firms since the 1970s appear to be "no".)
