TNG was definitely the peak of this. The crew of the Enterprise in that show don't turn on each other, make mistakes or do dumb stuff. This was an explicit rule by Roddenberry: in his utopia Federation officials never fought each other. The writers called it "Roddenberry's Box" because it was such a limiting rule, and the Box is why so many episodes feature mind-controlling aliens of various kinds.
Any post-scarcity society will look like communism/anarchism unless it is intentionally keeping part of its population poor for no good reason
I don't think this is true, see my other comments on this thread. Trek-style post scarcity where material things are non-scarce still doesn't cover anything non-replicable like people's time and attention, and by implication, service industries.
Until there is sci-fi that explains how a society eliminates scarcity of non-physical things like status, power and attention, the future will remain capitalist by default.
I think this stems from an idea of what socialism involves that even Marx would have dismissed as irrelevant and utopian.
In fact, Marx railed relentlessly against the notion of socialism/communism ending all inequality. One of the more famous cases of that being in the Critique of the Gotha Programme, where he criticises what became the SPD for even talking about "equality" without defining it precisely. This is where the (Bolshevik) distinction between socialism and communism comes from, though Marx talked about the "lower" and "higher" stages of communism, and argued that the lower would explicitly retain a lot of inequality, and that anything else would be unfair because people have different needs, and so inequality is according to Marx a pre-requisite for a fair society.
The point he made was that the goal was not to give everyone everything for free - instead he explicitly pointed to a then well established slogan: "from each according to ability, to each according to their need". The point being that his expectation - one he stated explicitly in the Critique - was that there would very much still be an exchange where peoples access to that seemingly endless material wealth is contingent on their participation in doing their bit keeping society running. He did not expect a true post-scarcity society, but one that met sufficient needs to eradicate class struggle, but which at the same time still had a need for people to work.
In that respect, the Federation strongly imply it goes further than Marx, in work being implied to be fully voluntary, and I do think we can agree there are plenty of unaddressed issues there. Though I think it's not that substantial, in that there's are many other ways of providing rewards than through material wealth, and there's nothing incompatible with socialist thinking in that.
My point, though, is that you have socialism and communism long before you get to that stage. Eradicate class struggle by eradicating the ability of anyone to monopolise production, and you have communism, irrespective of the specific details of how allocation of resources is arranged. Which is why you'll find communist ideologies that advocate for free market models and the like as the best means of making such a system work.
Will there still be exchanges of value? Sure. But those exchanges will necessarily look very different when everyone has the ability to access sufficient material wealth to be able to walk away from any transaction without fear of starvation or not having anywhere to live. That freedom is the point, not some notion of absolute equality in all things or entirely eradicating money.
And that is why I'm arguing that any sufficiently utopian/post-scarcity society will seem socialist. Not because there's no exchange of value at the margins, but because it's a small enough part of the lives of the typical person that being constrained by resources rarely comes up.
I think this description is flawed both with respect to Star Trek and The Culture. Nobody is flawless in either one of them. On the contrary, the stories very often focus on the flaws of people in these societies, often exposed in the intersection of these societies and a messier outside world, but also within.
> In Star Trek (as written by Roddenberry) the Federation is a society that doesn't use money, there is no internal strife, virtually everyone is moral and good with Picard being the apex human
TOS had a federation scientist introduce nazism on a planet because he thought it'd make them advance faster. DS9 showed a coup on Earth. There's been plenty of both internal strife and immoral behaviour showcased in Star Trek. A lot of the stories focus on overcoming their flaws, ranging from minor personality flaws, to outright bigotry (not just in the nazi example).
> The communist nature of Star Trek TNG/Voyager is quite obscure until you see it, and then you can't unsee it anymore. This is no surprise because Roddenberry's views changed in the decades between TOS and TNG until by the 1980s he was an avowed Maoist.
Any post-scarcity society will look like communism/anarchism unless it is intentionally keeping part of its population poor for no good reason. And if it intentionally refuses to share, it will look cruel and oppressive.
The distinction between a "communist utopia" and capitalism falls apart the moment you posit near-or-full post-scarcity.
So the choice then becomes one of whether the society you show is post-scarcity or not.

Consider that libertarianism started on the very far left: Joseph Dejacque, the founder of libertarianism, was an anarcho-communist who cheered on Proudhon's "property is theft" but denounced Proudhon for being a "moderate anarchist, liberal, but not libertarian", because a vision of maximal freedom that is positive and founded on an idea of eventually being capable of meeting all human needs will tend towards depicting a future where those needs are met for everyone.
> Obviously it's not a very serious essay but at the end I do wonder why there are so few optimistic depictions of the future. Even though the arc of human history has been solidly upwards, very little fiction is willing to extrapolate that forwards, and when it does happen the authors are always communists so we get weird, implausible takes on human nature that make humans feel more alien than the aliens. I guess it's because Marxism requires at its core an explicitly utopian prediction of the future to offset the rather less utopian consequences of bloody revolution. Whereas capitalism - being not so much an ideology as a thing that springs up naturally even when governments are trying to suppress it - doesn't have any kind of view on what the future will look like.
The challenge is that it gets harder and harder to create a positive depiction of a future with more and more material wealth that still chooses to leave some portion of society behind in scarcity. If everyone is "rich" then the distinguishing elements of such a society between socialism and capitalism becomes fewer and fewer until they become invisible.
