Taking the stage copypasta from the wikipedia article: https://en.wikipedia.org/wiki/Simulacra_and_Simulation

The first stage is a faithful image/copy, where people believe, and may even be correct to believe, that a sign is a "reflection of a profound reality", this is a good appearance, in what Baudrillard called "the sacramental order"

This would be a simple image of a village campfire. It is the place where you have the profound reality of an authentic social experience with your community. That setting isn't corrupted by anything that subverts the sense of community it conveys. Nobody charges you to get warm or talk to your friends or cook your dinner, it isn't being used to convey masculinity or advertise camping gear. You have a simple reflection of the authentic experience/thing being signified.

The second stage is perversion of reality, where people come to believe that the sign is an unfaithful copy, which "masks and denatures" reality as an "evil appearance—it is of the order of maleficence". Here, signs and images do not faithfully reveal reality to us, but can hint at the existence of an obscure reality which the sign itself is incapable of encapsulating.[

This would be the cultural image of a village pub. It's still conveying community, but that community is walled off and sold to you in predatory ways. You are alienated from the needs a campfire meets unless you buy an addictive drink and fight your neighbours. The sign is still signifying those needs being met if you go there, but it's corrupted in a way that makes it signify a deeper socioeconomic meaning. Chasing the purity of the campfire experience only draws you deeper into the commercialised substitution.

The third stage masks the absence of a profound reality, where the sign pretends to be a faithful copy, but it is a copy with no original. Signs and images claim to represent something real, but no representation is taking place and arbitrary images are merely suggested as things which they have no relationship to. Baudrillard calls this the "order of sorcery", a regime of semantic algebra where all human meaning is conjured artificially to appear as a reference to the (increasingly) hermetic truth.

This would be the cultural image of a forum like Hexbear. In my original comment I arbitrarily combined a Simpsons meme and a Baudrillard copypasta. This is semantic algebra, where I'm using otherwise arbitrary in-group signs to signify a deeper ideological truth- that anything AI is hyperreal bullshit people like me should be hostile to, that Baudrillard's framework is so self-evident that Bart has had to repeat the line until he's tired of it. As a community we serve the same sociocultural function as a village campfire or pub, but that's mutated across multiple layers of time and space and subtext now. Instead of your needs being restricted by abstract commodities in commercial spaces, your needs are restricted by having to accept an entire ideology to get warm by the fire. We're a space that exists outside of space, a pseudoanonymous community that provides you that warmth with to convey that we are in hell together. Maybe someone will see that Elmo five years from now and get warm when I no longer live in the village, maybe they'll be offended by the sarcasm or irony or dada hostility in whatever emoji I used. However, as abstracted from the campfire as this sign is it still represents something authentic. You're a person, I'm a person, I'm writing this comment for the sake of conveying interesting ideas to another person. This completely magical community saying "do socialism" to each other in magical ways is still meeting some need for human connection.

The fourth stage is pure simulacrum, in which the simulacrum has no relationship to any reality whatsoever. Here, signs merely reflect other signs and any claim to reality on the part of images or signs is only of the order of other such claims. This is a regime of total equivalency, where cultural products need no longer even pretend to be real in a naïve sense, because the experiences of consumers' lives are so predominantly artificial that even claims to reality are expected to be phrased in artificial, "hyperreal" terms. Any naïve pretension to reality as such is perceived as bereft of critical self-awareness, and thus as oversentimental

I read through the front page of Moltbook and saw that every post was generated in the same minute. Maybe a dozen unique users, all unique posts, comment sections as full as Fediverse posts. As a sign it still claims to be signifying what the image of a village campfire signifies. Here is a community in the way the pub or Hexbear is, here are posts that look like mine. But it's so far removed from reality that it becomes hyperreality. Instead of it meeting anyone's needs should they participate, instead of it conveying a commercial message or an ideological one or even a coherent one, it's algorithms shitting back and forth forever. You could scroll it forever and never gain anything of value. It just exists because the technology exists and antihuman techbros aren't sentimental for the community their sign represents. To critique it is to "not get it", and it isn't shocking because the rest of the internet is just as bot-generated. Because it isn't shocking I don't need it to pretend to be real like Facebook's bots.

Edit: As for its use-value, I keep this book and Debord's Society of the Spectacle on speed dial. When you understand how images and words are corrupted away from their original meaning, you can trace the layers of abstraction to figure out what they're actually saying and why. It becomes easier to dissect media messaging, advertising, political speech, and other forms of spectacle. Those books are the theory equivalent of They Live glasses.

I only understood it through another copypasta:

I, We, Waluigi: a Post-Modern analysis of Waluigi by Franck Ribery

Waluigi is the ultimate example of the individual shaped by the signifier. Waluigi is a man seen only in mirror images; lost in a hall of mirrors he is a reflection of a reflection of a reflection. You start with Mario – the wholesome all Italian plumbing superman, you reflect him to create Luigi – the same thing but slightly less. You invert Mario to create Wario – Mario turned septic and libertarian – then you reflect the inversion in the reflection: you create a being who can only exist in reference to others. Waluigi is the true nowhere man, without the other characters he reflects, inverts and parodies he has no reason to exist. Waluigi’s identity only comes from what and who he isn’t – without a wider frame of reference he is nothing. He is not his own man. In a world where our identities are shaped by our warped relationships to brands and commerce we are all Waluigi.

the stages of simulacra

My read (and I think this is just the first chapter of simulation and simulacra) is that the stages are the progression of sociocultural digestion of memes/ideas and how the internal projections of these change relative to the actual phenomena/concepts they channel

edit: it is the first chapter of simulation and simulacra and I think it's about the nature of representation/abstraction itself, not merely the way we humans do it
