Cyberpunk is now. High tech/low life? Here I am, Mr. Working Poor Man with multiple fancy light boxes and access to a massive network of communication and knowledge. Rampant capitalist exploitation and control to the point that the interests of "big corporations" and "government" are practically synonymous? Check. Near-complete social control through constant psy-ops and the usage of new tech to turn people against eachother by reaping greater rewards on top and fucking the little guy a little harder? You betcha. I mean, for Eris sake, nicotine and weed? Electronic. Meth and heroin? Pills. The modern tech industry? Literally so robust that fucking fake internet money mining operations actively contribute a notable to the destruction of our climate.
All we missed out on are the cool aesthetics that the modern media's idea of the genre focus on (i.e. "crazy futuristic tech," neon megacities, and technological augmentation/prosthetics better than organics) because those are the parts that we don't actively live in. It has to focus on being boiled down to the aesthetics, because otherwise it seems too eerily like a story set a single-digit number of years away.
It's important to remember the "punk" in cyberpunk-- it is, at its core, a logical extrapolation (and therefore harsh criticism) of where the neoliberal system is headed-- and thus uses certain levels of hyperbolic metaphor to define those criticisms of the system. For instance, maybe the "Corpos" don't have an army of physical androids and mechs to physically crush resistance, instead, irl the Capitalist class uses a mix of online bots and human "robots" who've been radicalized into System-ism.
Cyberpunk is, at its core, a telling of one possible future in which people maintain the Status Quo for an undefineable about of time, to the point that every possible material condition has run to its endgame of literally a full 100% of the power and wealth in the hands of the top, and nothing in the hands of the great many, and no way to fight back, a-la the Gilded Age ramped up to a hundred when nobody fights back at the point they did last time.
@MorphedSnowman above me makes the point that cyberpunk's criticisms fail in that they never see the world change, but that
is the criticism, or part of it, at least. That if the current mindsets and ways of living in which profit and desire of the few are prioritized over the material quality of life of the many continue on, that we
will reach a point where change genuinely cannot be achieved, that the only hope that the average man has for survival is just what you mention- pure fuckin' luck combined with natural aptitude.
The real cyberpunk question is, are we all the way there yet? And if we aren't, is there even still time to stop it?
