No, you're wrong. The Soviets were quite advanced in industrial technology. So much so that they turned a backwater, under industrialized agrarian society full of Russian hillbillies, into a nuclear superpower, rivaling the United States, the most powerful empire in human history. The US had a 120-year headstart in industrializing itself, and yet the USSR was able to survive the onslaught of being invaded by the United States, the UK, France, and 12 other countries between 1918 and 1926. Over 200 thousand foreign troops, with over a quarter million anti-socialist Russians of the "white army", fought the red army, and lost. The USSR was at war, from 1917 to 1991, with only maybe a decade of relative peace in the 1930s.
The USSR was invaded by 4 million Germans in 1941 in Operation Barbarossa. The full brunt of the Third Reich's war machine was focused on the Soviets, not the Western front. Seven out of every ten Nazis were fighting in Russia. The Soviets lost 27 million of its citizens in WW2, about 14% of its population. The United States lost 460 thousand people, 0.03% of its population. The US is surrounded by two vast oceans, making it practically impossible to invade, especially in the modern age, due to naval technology and the size of its territory and population. The odds of any country successfully invading the United States are about nil. The US came out of WW2 unscathed, compared to Europe and Japan.
The Soviets lost a significant % of its national infrastructure in WW2, being that most of its population was in Western Russia, not in Siberia. They didn't have the American-backed "Marshal Plan" as Western Europe and Japan had after the war. The Soviets had to rebuild their new country, by picking themselves up by their bootstraps, and indeed thanks to Socialism, they rebuilt the USSR into a nuclear superpower, with the second largest economy in the world, not to speak of its military capabilities.
That bears witness to how effective socialism is in industrializing a nation. Many Western, non-Marxist economists admit to the fact that socialism industrializes and builds national infrastructure quicker than capitalism. It's extremely effective at doing that. The Soviets were the first to have nuclear plants, connected to a power grid. They were launching satellites and people into space, before the United States, less than 15 years after the cataclysmic devastation they suffered in WW2, losing tens of millions of their citizens and much of their infrastructure.
You shoot yourself in the foot when you start mentioning the USSR when debating communists like me. You shouldn't mention it and just stick to arguments based on present-day socioeconomics, lest you get clobbered. I can debate five capitalist apologists at once, due to how stupid their arguments are. I'm not smarter than them, that's not why I win practically every debate on these issues. I rip their arguments to pieces because I have the truth, not because I'm more intelligent or better than them. I just open the cage and let the lions out. They do the job for me. Defending communism is easy, against capitalist-imperialists.
If you want to delude yourself into thinking that the automation available in the 1960s, was as capable as what we have today in 2023, with our present technology, hey believe whatever nonsense toots your horn.
Automation is taking over like never before, eliminating jobs, at an unprecedented scale, and the wealthy ruling elites know that They understand what is happening, they're not idiots, hence their pleas to their cronies in government to hand everyone a monthly UBI i.e. Universal Basic Income. That government check (socialism), is what these billionaires are hoping will save capitalism.
Within the next few decades, society will be forced by necessity to adopt a non-profit system of production, no longer based upon profits or markets, due to unemployment. Advanced 21st-century automation technology, ensures the victory of socialism over capitalism. It reveals socialism as the natural, inevitable successor of capitalism, just as Marx and Lenin taught us in their writings.
