USSR just wasn't rich enough to afford experimentation and innovation. Resources (including human brain power) were quite limited. So they had to copy proven solutions. Simple as that.
It's easy to judge them in the retrospective. But they had to make decisions, using the information the had at the moment, weighing risks as they saw them at that moment.
Of issue, especially as time went on, was the overly-centralized nature of national resource and economic strategy and planning. Especially ESPECIALLY constraining was the dual-circuit monetary system of its economy, which literally prevented half of its "capital" to follow innovation or market forces outside of centralized allocation.
I highly recommend the book Collapse: The Fall of the Soviet Union by Vladislav Zubok
The USSR and the Iron Curtain bloc had a massive population and world-class scientific talent. The problem was that the Soviet system viewed independent thought and individuality as a threat, actively sabotaging its own geniuses:
Persecution of Top Minds: Sergei Korolev, the literal architect of the Soviet space program, was sent to the Gulag, where he lost his teeth to scurvy and survived a broken jaw before being pulled out to work in a sharashka (a prison lab). Andrei Sakharov, the father of the Soviet hydrogen bomb, was relentlessly persecuted and exiled later in life for pointing out systemic flaws.
Ideology Over Reality: The state actively banned the teaching of modern genetics for decades because Trofim Lysenko’s fraudulent agricultural theories were deemed "more communist."
When you look at where the USSR did choose to spend its massive resources, it wasn't on pragmatic, cost-saving solutions. It was on hyper-expensive, top-down military prestige projects—many of which the West mathematically evaluated and discarded as impractical.
They built the RBMK reactors (like the one at Chernobyl) specifically because the dual-use design allowed them to generate civilian electricity while simultaneously harvesting plutonium for weapons, creating a fundamentally unstable system. They spent fortunes building the "Caspian Sea Monster" (a giant ground-effect vehicle) and the Tsar Bomba.
The tragedy of the Soviet computer industry wasn't a lack of money or smart people. It was that any "von Neumann" or "Seymour Cray" born in the USSR who asked the wrong questions or challenged a party bureaucrat's stupid idea was far more likely to end up in a labor camp than heading an independent tech company.
Those born in countries like Poland, Hungary, Bulgaria or Czechoslovakia were usually "asked" to leave country and they were working for the West ;-)
It was more that the RMBK was more designed around existing Soviet manufacturing capacity, they could and did build more conventional reactor designs as well but they required enormous pressure vessels the USSR only had one factory to produce. The RBMK on the other hand is not a monolithic pressure vessel, it's a collection of hundreds of individual pressurised tubes which were much easier for the Soviet manufacturing base to produce. It was actually a clever idea on the face of it, the problem was more it had inherently dangerous behaviour in certain regimes (the infamous positive void coefficient of reactivity) and the positive scram effect wasn't known until well into their deployment. The operators were also given contradictory operating instructions which failed to highlight the safety-critical nature of certain parameters.
One famous example is Jacek Karpiński [0]. Soviet pressure, opposition to the use of Western parts, and intense jealousy of the commie state bureaucracy which sought to hold a monopoly over computer production (e.g., through the state-owned companies Odra and Elwro) halted production.
Here's some English language documentation for one of his models (the K-202) which was exported to the UK [1]. (The state-produced Mera 400, a heavily modified version of the K-202, did achieve a great deal of success, however, despite high production costs.)
There was an article posted here about him about 10 years ago [2].

It's worth noting that Poland was actually one of the least ideologically rigid countries in the Eastern Bloc. While you couldn't openly oppose the regime, it was entirely possible to have a brilliant career in science or medicine (like Zbigniew Religa, who pioneered Poland's heart transplantation program) without strictly toeing the Party line.
Yet even in Poland's relatively relaxed climate, Karpiński’s revolutionary K-202 was strangled by bureaucratic jealousy, state monopolies (Elwro), and the paranoia of central planners.
If that was the fate of an innovator in Poland, imagine how much worse it was inside the borders of the USSR proper. The Soviet system operated on a near-literal interpretation of totalitarian control, where maintaining absolute party monopoly over every facet of life was prioritized above efficiency, wealth, or technological progress.
In that environment, independent thinkers weren't just seen as eccentric or inconvenient—they were viewed as a systemic security threat. When a system treats structural innovation as a form of ideological deviance, the safest thing for a genius to do was to keep quiet, escape to the West, or risk ending up neutralized by the state. You can't build an "alien spaceship" computing paradigm when the system's primary metric of success is total bureaucratic obedience.
I really wanted an MSX looking box though, that we played Karateka on in some precursors of Internet cafes, they looked the business, like high end Japanese hifi gear of the era.
> USSR just wasn't rich enough
To an extent by choice. They really didn’t utilize the resources they had optimally.
The first is corruption. When the Iron Curtain fell, every country behind it suffered from corruption. The Russian word for how it worked was блат, pronounced blat. When the official way of doing things doesn't work, the way that works is informal favor trading. I have a friend, who knows a friend, etc. This acts as grit in the economic system, and makes everyone less productive.
The second was the pressure to not stand out too much. One proverb is Инициатива наказуема, pronounced initsiativa nakazuema. It translates to, "Initiative is punishable."
Why? Well, imagine that you're a middle manager. It's a dog eat dog world. You know that everyone below you, wants your job. Everyone above you, knows that you want their job. You got your role by sucking up to the people above you. Those below you, got theirs by sucking up to you. You don't want your employees to be utterly incompetent - then you won't be able to look good. But you also don't want any of them to shine - then your boss might think that they should have your job. This encourages bland mediocracy. Everyone strives to be just good enough for their job, while sucking up well enough to keep it.
The result is a kind of learned incompetence. But a nation filled with this kind of incompetence, will be unable to sustain innovation.
The third is alcoholism. Russia is basically a very large, very dysfunctional, alcoholic family. It is hard to overstate how true that is. The most popular vodka at the end of the Soviet era came in 750 ml bottles, that did not have a resealable cap. Because no true Russian would leave a bottle half-full. Anyone who didn't drink, was odd. A group that got together without drinking might be suspected of plotting revolution. This is yet another drag on Russian society.
