I'm non-spiritual, though I do believe something similar to dualism* in an abstract sense (I see it more as 4*, along with different levels of granularity depending on the type of interaction). Though in reality also am about as disconnected as one can be (so I'm not even on the chart).
Transhumanism: leave my brain intact (remember: no copies) and I'd roll the dice if I could do so without techbros. Ideally I'd have more microbiomes/(types of)living cells to keep me alive and stable+clean (and synthesis maybe) rather than the tech-only life-support model often seen in sci-fi.
Somewhat disagree on food, I think cooking is a useful skill and can see utility in art and celebration. Though yeah that's less-and-less common for me, I've eaten a lot of not-great frozen burritos. Even if I didn't need to eat food, I think it'd be nice to have an excuse to eat decent food at least sometimes.
EDIT:
* I'm not actually sure if dualism/non-dualism is the best term here (I'm talking about organisms only, not mind/body or rocks etc). The 4 I mention is roughly: self, other, friend, unknown. Something like a jellyfish would be the unknown. Though things can move in that chart, and will obviously be different for survival vs society.
