The suggestion to use AR glasses with this keyboard computer feels very Ghost-in-the-Shell cyberpunk to me. Stepping onto a train and you find some guy with glasses sitting near the train door staring blankly at other passengers while typing furiously on the keyboard. Looks a bit creepy. After a moment it's revealed he has an AR display and he's writing an email or whatever.
...why do I feel nostalgic for a cyberpunk dystopia?
I think IRC would slightly enhance the cyberpunk aesthetic, and is likely to give strong competition to email for the 'eternal communication protocol' contest!
