Away from screens, I'm doing hobbies I picked to actively keep me away from screens. On a motorcycle, I think my ego gets sufficiently preoccupied with keeping its physical host alive, and so then the rest of my mind can wander. Depending on flow state, the mind speaks language, symbolic memories, or in sufficiently intense activities, those disappear entirely and it's just sub-second sensory immediacy.
In language, it's a lot of comedy (e.g. How could you tell if someone you already knew was wearing a disguise? How would they respond if you asked them? How would you know they aren't? What if they're lying? When you solve a catchpa to prove you are not a robot, how sure can you be, and who are you trying to convince, really? etc.) then, it's ethical and religious questions about power and politics (What is a just war? Is deception intrinsically more moral than violence? Do leaders have a divine mandate? For what are we accountable in regard to good and evil? What is the substrate of our experience? Is "The Simulation" just language?), and then some of what most closely resembles adolescent metamathematics (What are the most atomic operations and what property of the universe makes their number finite? Is complexity an artifact of geometry? What isn't a graph?)
The rest is too long to get into, but essentially it reduces to whatever deepity is sufficient to distract me from doing the work I'm probably supposed to be doing.
