I honestly believe the closest thing to real world cyberpunk is the anti corporate / foss / selfhosted digital sovereignty “ideology” that lemmy coincidentally is a part of. For the rest, like cyberdecks and body augmentation we just have to wait a bit.
Let me preach you the gospel of sleeping twice a day for 4-5 hours. I used to have a real slump around (after)noon to the point that i would fall asleep sitting in a chair, naturally resulting in back/neck pain. Now i just take a nice long nap whenever i feel like it, waking up to a refreshed mind.
