The thing is, cyberpunk was a fear of a Japanese corporate takeover, but it was actually a fear of a lot of other stuff. The automoton cubicle farms that we'd force people into, basically livestock to feed the corporation. The disillusion of identity as we increasing replace our minds and body parts with cybernetics (a human ship of Theseus), not to mention the personification of computer creating literal identities out of machines. A fear of multiculturalism replacing cultural identity with a mish mash of things, ultimately creating a schizophrenic identity that is everything and nothing at the same time. The breakdown of society, where the dregs only barely to manage to hold on to their self identity as outlaws, working against a system trying to assimilate them.
Cyberpunk is the anxiety of the 80s given form, and amazingly, probably the most accurate science fiction genre there has ever been. Not just in predicting technology like the internet, but also in the replacing individual identity with group identity through an obsession with social media. Our iPhones aren't technically part of our bodies, but for most people, they might as well be. And the reality inside those little computers is perhaps more real than what happens in actual reality. With the way we are ostracizing people in favor of group think, it is increasingly becoming the outlaws (the non-PC) which retained a sense of individuality, all the while corporations are encroaching into the personal aspects of our lives to create better consumers, hiding behind slick glamors. How is Wikipedia and the email leaks showing our politicians to be corporate stooges any different than the cyberdeck cowboys in Neuromancer, trading information as currency?
I mean, we're there. Cyberpunk is only the future in its excess, not its ideas.
Frankly, if you look at cyberpunk and the only thing you take away from it is that "we be scared of Japanese people, yo", then you missed the entire point of the genre. The point is that we are scared of everything, and justifiably so, as corporations and technology replace us, bit by bit. But if you grew up with corporations are your nanny, connected at all times to the internet and invisible personas pretending to be real people, you might not know why the 80s were afraid of this time and what they were trying to warn against.
