I find the notion of a coherent self / consciousness to be hogwash anyway. The "self aware" "conscious" brain is a wholistic entity, with what you ate yesterday causing moods that alter your train of thought etc etc, with multiple competing interests vying to control the larger organism to their own ends. The Ship of Theseus is the warmed-over Christian heresy. A brain is an organism with a symbiotic tight coupling to a meat bag, and the brain itself a similar cooperation by accident. An organism can develop that builds new tight "synthetic" couplings; it isn't sci-fi. It's partially released today. It's just that we are so normalized to the interfaces of smart phones, keyboards, monitors, steering wheels, and so on that we didn't notice it's arrival. More exotic, more tightly coupled interfaces also exist today (there exist direct-to-brain interfaces that provide a new sensory feedback loop that you brain can adapt to), they're just not as competitive currently with thousands of years of neural optimization of hands/eyes/nose/touch. Why would you want to do this? Who knows. Why do we want to do anything? Maybe a person wants to be part machine as a lizard-brain driven reaction to a low-oxygen office environment that sees no viable way out.
