In my case I use the same ringtone as in 2077, use ChatGPT on my phone, have neon lights as decoration, wear Techwear from time to time, use encryption wherever I can (even just for fun) and I am a Corpo Rat by day … let me know what you do to feel more Cyberpunk?
Host my own VPS with docker containers running everything I possibly can to host myself.
Additionally, I also hack gear, take Nootropics (somewhat) and try to get into unsecured networks for a laugh ;).
