A lot of the concepts in cyber punk did come true, the corporate consolidation, only 6 corporations run things you know, and as time goes on it will probably be whittled down. The government is an oligarchy, they are controlled by corporations, wall street, lobbyist groups. China is rising, although its not Japan, the importance of an east Asian culture is also rising. You look at groups like Boston dynamics their videos are pretty much the robots that will be normal in everyday life 50 to 70 years from now.
The government has developed exoskeletons and high tech iron man armor to make future soldiers more powerful. The corporate government is in a constant battle with elite hackers from outside and inside the west, wikileaks, guccifer, anonymous, lulzsec, etc.
Look up something called "the internet of things" , soon everything will be powered by the internet, and that will be exploited by governments and bored 16 year old Russian hackers.
Think about the near future, what happens when 3d printers are ubiquitous, what if you printed out your own solar panels and didn't have to pay an energy bill anymore?
Think of video games, they started out as pong but now they are hyper realistic, now think of VR now, how will that be in 50 years?
Think about self driving cars, think about being able to call a self driving car with your smart phone and paying it with bitcoins.
Right now there are giant metallic birds called "Drones" that are used to kill terrorists and are being experimented with to deliver pizza.
Look at these videos, we are getting so close to perfecting robotic prostheticshttps://www.youtube.com/watch?v=KPhkVPNKtVAhttps://www.youtube.com/watch?v=_qUPnnROxvY
A lot of what was written in cyber punk stories came true, some didn't. And as time goes on maybe more of it will.
Science fiction is supposed to be about the future, well the present seems to be increasingly a cyberpunk nightmare.
