Any moving part is going to wear out eventually, probably not last more than a decade if it's always in use. And everything else is subject to wear from temperature changes. The human body isn't that bad at maintaining itself in comparison. Just need to be able to grow new organs for the long term.
I have ship of thesiused the same NAS now for 15 years. Just get a hardware maintainance plan. The best bit is it gets cheaper annually.
IMO, a computer could be me but I would never be a computer.
Hook my brain up to it (/into a toaster-sized cyborg body) for a different/better life experience, but I wouldn't really be doing it for longevity. A fixed up body would be nice, but I'm not really attached to the idea when I could just exist in inhospitable environments (or a digital life without a physical body to worry about).
I think we could eventually "Ship of Theseus" our brains to hardware and eventually software (thinking protein-based "walkers" along neurons that copy nodes and IO strengths to build a graphene/nanotube-based memristor network with interfaces for current connections to existing neurons as well as interfaces for eventual software conversion), which would thus maintain continuity of consciousness and I'd feel better about it actually being me instead of "just a copy".
Really I just want to get to the point where I can remotely control either a physical or digital avatar at will, without having to worry about my existence ending. Bonus feature: I might be able to extend myself to control two or more avatars simultaneously, or be able to communicate with similar minds in a much faster manner, creating a much faster, more comprehensive form of intelligence.
If scientists can't point at the bit of brain meat that is consciousness, I'm just gonna leave it alone. I could maybe justify adding math understanding, but even then the need for that is already low with computers especially if it were hooked into my brain.
I could be in VR headspace writing on a chalkboard whenever needed.
I assume I could even temporarily "overclock" my brain to some degree if needed (read: thinking really hard/changing perception of time in the same way that we already experience naturally or via substances), in the same sort of management like sleeping one half of the brain.
Automated teaching and targeted learning could probably also be a thing. Or sleep/dream supplementary learning. Or simply VR lectures (like a video but slightly better). Learning this way would already be easier as there wouldn't be distractions/upkeep for an organic body (what body there is would have automated upkeep, though you may still be distracted if something unexpected happens).
