Brief description
The Optik is a a device that all citizens must wear, which taps into the optic nerve and shows an AR display of the world. Earlier prototypes were glasses, but the current version is a biochip. It's connected to an AI assistant called Bagley. It's described as the most important device since the smartphone, and it lets the user see their "emails, take calls, and browse the internet as if the screen was in front of your eyes." The Optik is also connected to the public transport system and wider national and international registries, so you don't have to register or prepurchase a ticket to go on the Tube and you don't have to carry a passport.
