You can use FOSS without knowing how to code though. I wasn't completely serious I know Marx didn't predict FOSS but I do think it's an example of how the means of production being shared could look like. It would be great if that also included open hardware as well.
Edit: I realize it means the workers doesn't actually own the means of production but it's a step in that direction and I don't think it contradicts what Marx said is my point.
Marx wasn't a technological determinist though. He believed that a workers revolution would bring the end of capitalism. He even thought it would happen druing his lifetime.
Marx did talk about individuals owning the means of production. For example farmers or craftsmen owning their tools before capitalism. Marx talked about the means of production being shared under communism and not owned by one specific person or capitalist. If anything Marx predicted FOSS lol.
No country has ever claimed to achieve it but there are societies both past and present that have created similar societes. Like chiapas in Mexico and Rojava today.
Communist China is the closest to what you might you believe in
Either you didn't read what I said or you know nothing about communism. Also like what is with people not understanding that no country has ever claimed to have achieved communism? It's just an objective fact China or the Soviet Union for example never claimed they achieved communism.
No country has claimed to have achieved communism. Many other places have tried but it's usually crushed by capitalist or sometimes even by states claiming to be socialist. It's also a really simple and tbh ahistorical explanation to claim that communism didn't work simply because "it was confronted with reality".
Communism focusses too much power in too few positions
Literally the opposite of communism
Maybe take a couple of deep breaths and calm down before you post on the internet? It's an example of self-governed autonomous and democratic communities. If you disagree with that maybe you can explain why it's wrong instead of throwing a fit. Also, maybe you should read up more on what you're talking about because you didn't even use the correct name nor seem to know the meaning of the word Subcommandante.
