I doubt that. In my utility function as it is now

This "utility function" is just an intellectual construct - I could even call it an ideological construct, the ideology being "I must not die, and I must not believe anything which might make me accept death, under any circumstances" - and has nothing to do with how you would actually choose under such harsh conditions. For that matter, the whole idea of literally never dying is not in any way evidence-based, it is pure existential determination.

You are unusual in having wilfully chosen both Christianity and transhumanist immortalism. I know another transhumanist who converted to Islam, so maybe this combination of traditional religion and secular techno-transcendence has a future sociologically.
