I’d look to Swiss army knives for inspiration. Knife, screwdriver, scissors, pliers. A light. Someone said phone holder… I’d have the phone embedded in the arm, positioned to be easy to see and access. Have the lock screen be various health stats: heart rate, Vmax, Time. Usb charging port… Be able to both charge the arm, and charge devices from the arm, maybe with a retractable cable ala cyberpunk 2077. Camera in a fingertip, ideally connected to XR glasses, so I can see behind or under things easily, able to be a microscope. Electric arc lighter in another fingertip.

It certainly feels like that at times. The key being the non verbal part, it’s the part that feels things i can’t explain, like I have to poke and probe some part of my brain by imagining, to try and see how it reacts to certain thoughts and observe the emotions, then try to put it into words to explain it to the conscious part of my mind. Like, the subconscious is not unconscious, it’s perfectly conscious just not verbal.
