I think it's a mistake of false dilemma to say, "Not capitalism, therefore communism!" because the options/choices for economic systems are broader than communism or capitalism.
No capitalist country today is "pure" capitalistic. They all pretty much have a mixed system, where state is supposed to regulate the market and provide some welfare to the more economically vulnerable. Some countries do it more, some less.
If we're talking about a succeeding system to capitalism, and nore merely reforming capitalism which has been done time and time again, and it's not some form of socialism, then what do
you propose it will be?
I mean, in your original post, you said :
When the costs of production have essentially been reduced to zero, why maintain a monetary system at all? What's the point? When the costs to produce something have been reduced to nearly zero, why not just make everything free? What would a society look like where anything anyone could ever want is readily available? The notion of material possessions becomes kind of meaningless. Who cares if your neighbor has a 52 inch television, when you could order one and get it at any time you wish? The concept of measuring worth by material possessions becomes antiquated. When our daily pursuits for mere survival are replaced by pursuits of leisure, I think the natural human tendency is to become creative and to share our creative works with each other (game development being one of those creative pursuits).
What you're describing is...communism, dude. Like, straight up. Why does the mere word scare you? A stateless, classless, "everyone according to their needs" post-scarcity society is exactly what communism is.
https://en.wikipedia.org/wiki/Post-scarcity_economy#Marxismhttps://en.wikipedia.org/wiki/Communist_society Marx's concept of a post-capitalist communist society involves the free distribution of goods made possible by the abundance provided by automation.[26] The fully developed communist economic system is postulated to develop from a preceding socialist system. Marx held the view that socialism—a system based on social ownership of the means of production—would enable progress toward the development of fully developed communism by further advancing productive technology. Under socialism, with its increasing levels of automation, an increasing proportion of goods would be distributed freely.[27]
This is, like, exactly what you described in the post I quoted, but at the same time you say "it doesn't have to be communism!", merely because the word itself scares you because of its associations. I don't blame you entirely. But the (future) society you describe already has a name.
You guys realize "Communist Russia" didn't ever actually *achieve* communism or even came close to it, right? It was called "Communist" because it was ruled by the Communist Party whose stated goal was to reach communism at some unspecified point in the future, after overthrowing capitalism and passing through the necessary(according to Marx-Lenin) states of socialism and "dictatorship of the proletariat" and all that. No official of the Party in their right mind ever claimed they had achieved communism. That would be entirely laughable, considering that, by definition, a communist society is a stateless one, and they would have to dismantle the Party and the State in that case as unneeded and obsolete. :P
I get your point that the initial post was about how sustainable capitalism is as a system, but you can't really keep real-world politics out of discussions like this.
But anyway, if we're going to steer the thread back on course, let's consider this, because yours is hardly a new idea :
Marx did not believe in the elimination of most physical labor through technological advancements alone in a capitalist society, because he believed capitalism contained within it certain tendencies which countered increasing automation and prevented it from developing beyond a limited point, so that manual industrial labor could not be eliminated until the overthrow of capitalism.[28] Some commentators on Marx have argued that at the time he wrote the Grundrisse, he thought that the collapse of capitalism due to advancing automation was inevitable despite these counter-tendencies, but that by the time of his major work Capital: Critique of Political Economy he had abandoned this view, and came to believe that capitalism could continually renew itself unless overthrown.[29][30][31]
So, basically :
1) Elimination of most physical(or even menial-repetitive intellectual one, due to AI) labour will inevitably come through technological advancements alone, so we basically wait until that happens, capitalism grinds to a halt because of this, and then we replace it with a more sustainable system that allows everyone to enjoy the fruits of this technology.
or :
2) Capitalism will find ways to re-invent and reform itself, limit the technological advancements and their application exactly in order to avoid breaking down, and if we want this post-scarcity society to happen, political action must be taken in order overthrow capitalism and replace it with a system whose stated goal will be to reach this post-scarcity society as soon as possible, and not avoid it.
