I think it's rather cyberpunk that have Japanese esthetics not the other way around :)

I know several people with RFID implants. The Apple Watch collects health metrics, among a other things. A guy had a Bluetooth speaker implanted to cheat exams in India.

I think the most dystopic example is the Poor sods whose bionic eyes ceased functioning when the company folded.

Yeah, ok, an RFID implant is cool, but it's just something embedded under your skin, so a far cry from a computer interface implanted in your brain...

Tbf the 2.0 aspect was almost purely aesthetic, but saying that in that article there is a specific mention of things like phones and other tech that's so ingrained in the society in way that wouldn't have been imaginable in the 80s during the OG cyberpunk period.

Implants are not a thing because there's already a much better alternative in the form of highly portable devices that can be easily replaced. Unless there's a specific use case where a device needs to be inside the body, it won't happen.
