One of the core things about schizophrenia is a loss in touch with reality, as if the suffering is literally in a world of their own. It might be that this world for SparrowOS doesn't do him well in everyday life but may be very helpful with endeavours which require a leap in thinking. The OP does have an interesting question because a characteristic symptom of schizophrenia is a loss in train of thought. This seems apparent in his posts because they seem, in a lot if ways, to diverge away from the actual topic (such as meeting God, which also demonstrates delusional thinking). It's interesting because such losses would make it hard to sit down and focus on writing something coherent, which seems like it'd apply to programming just as much as writing and speech. Though, if he becomes very lucid when discussing CS stuff, perhaps programming as an activity itself provides that lucidity. Programming may be his therapy. Occupational therapy is often pushed in mental hospitals (I speak from experience). Either way, it's not even a good idea to try and approach, even it with the best intentions, for you don't know of the damage you may be causing. It's hard to believe but you have to be very, very careful of what you say or you risk furthering his mental health problems. It sounds cruel but the best thing would be to let them be, or at most focus 100% on CS. I speak from my experiences as a mental health patient and becoming very close friends with a schizophrenic.
