The sad truth about communism, well not counting the mass murder and gulags....

Not necessarily. It is tyrannical by design. What right does the state have to confiscate your property claiming you have no right to "control the means of production?" You invested your time, your resources and your abilities to create that "means of production." You have no right to that? Someone who invested their time and resources to getting drunk in a bar has as much right to your resources as you do? That's both the theory and the reality. When beloved Fidel Castro died, his family was worth almost a billion dollars. Hugo Chavez died a multi millionaire. Maduro was said to have personal wealth approaching a billion dollars, while the common man starved.
The history of a mixed economy is not good. If you make a bad decision for your company, you have to get the resources to keep things afloat (for example, relinquish full ownership by taking on a partner or investors) when a government entity fails, the government just pours tax dollars in to cover their mistake. If a business fails and goes to bankruptcy, the assets are sold, and other business owners generate income from those acquired asset, it's not a net zero. When the government fails they keep the failure alive with tax dollars.
Not a direct example but look at the Selective Service for a government example. When was the last time we had a draft? March 12, 1975. Mandatory registration continued but our armed forces have been volunteer since then. What is the government response to this no longer needed agency? (2017): employed 124 full-time civilians, 56 part-time civilian directors, 175 part-time reserve force officers (in peacetime), up to 11,000 part-time volunteers with an annual budget of $31.3 million (FY 2024).
Young men no longer have to actively register, it's all done automatically with computers. All this for something we haven't relied on for over 50 years.
We constantly hear, communism doesn't work because it hasn't been tried in the right conditions. If capitalism doesn't work, it's because it hasn't been allowed to function naturally since Woodrow Wilson.

I can't wait to see how AI does ruling us.

actually, capitalism does work.
its not great for some people, especially workers who are exploited, but it has been proven to work in a democratic setting. again, a better solution would be a mixed economy.

Exploited- never ever happens in communism. History shows the exploitation of people in communist nations is 100%. Gulags for no reason, gulags for saying something the tyrant class doesn't like, executions for thinking "outside the box." When communism "fell in" Russia , McDonalds was among the capitalist pioneers to re-introduce capitalist principles to Russia. At the Grand Opening in Moscow, the doors were opened with 10 lines ( it may have been a different number- but a large number of order takers) to serve the customers. The unexploited united workers all stood in one line as was the custom in the abundance of the worker's paradise, even as the order takers tried to welcome them to freely place their order at an open lane. People went through the lobby explaining to the workers in paradise they didn't have to stand in one line, there was enough food for everyone and they were free to go to the shortest line. It took months for the unexploited workers to understand the abundance provided by capitalism. Look at any worker's paradise, unencumbered by capitalist exploitation and you see one line, shortages of products and prices that prevent the freedom of savings and accumulation for personal wealth to say fund a better retirement. Only elites can send their children to college.
In the mixed economy or "Post Communist" Russia, "investors" like Putin and other politboro members attained great wealth while the unexploited workers continued to wallow in poverty, and lagged behind the prosperity. The concept of a "mixed economy" is a myth pushed by subversive communists. We haven't had true capitalism, which allows an exploited worker to go to work where they are not exploited, to get training for a better job, to relocate to an area of opportunity, since Wilson and FDR, when communist revolutionaries infiltrated the highest levels of our federal government and disrupted our economy.

you say russia is bad for its mixed economy, but that is not true. it is bad for its dictatorship. a country with a mixed economy is norway, a WESTERN nation who is the 7th happiest nation on earth. theyre also quite rich. doesnt sound quite bad, does it?
