CyberneticPunk is a rather modern aesthetic though the things that influenced it are from the 90s. It's orientated around a gritty depressing existence and a state of being 'terminally online. Old work machines. Haphazard cables. The abandonment of the physical body and flesh due to uploading your consciousness onto the Wired (the sum of all human communication and networks). Which is where Serial Experiments Lain, a 90s anime comes into play. This aesthetic is less staged images with nice filters but more low quality or authentic images so essentially serving terminally online weeb realness. It also doesn't shy away from using things like wojaks or other memes.
It is also often linked with things like Accelerationism, Anarcho-Transhumanism, CyberNihlism, and XenoFeminism. On twitter it is also linked with a community called SlimeMoldTWT which posits the idea that since there are no justified hierarchies, that one must become slime as the skeleto-motor coordination system is 'authoritarian' and so on. This is where the green circle emoji in people's display names comes into play. As it is anarchist, it also ends up tying in with concepts like three printing of regulated items, Counter-Economics, Bitcoin, and Crypto-Anarchism.
Due to this, it often also includes aesthetic elements related to the books Fanged Noumena, Meltdown, CCRU Writings 1997-2003 ie the Numogram, the cover of Fanged Noumena, Neo-China, the superiority of technology, and the extinction of humans at the hands of AI. And also to the works of Deleuze which is why often jargon used by Deleuze is common. So this means words like 'Body without organs' and 'Deterritorialization'.
"Nothing human makes it out of the near-future"
It is also important to note the Neo-China aesthetics and also Sinofuturism are utilised sometimes, the later having been described as a science fiction that already exists.
