@syvarris On happy-flesh:
Because, for example, one might want to settle down eventually and have children (come on, there is only a chance of sterility, right?)?
But honestly, yes, I'd agree that temp-botting and then maybe getting back your body or growing a new healthy one might be the best "practical" choice. I say "practical" because there is one more practical matter to consider, and that is - it does not matter if you remain physically alive until the end of the war if you end up completely deranged by then. All in all, fleshy bodies are an excellent deterrent to issues of existential origin, which can kill a person more surely than a bullet. What for to keep living if nothing is real? How can one be sure that what you experience around is actually real - especially since you can know for sure that this is a body made by humans, and it might be flawed - or, more importantly, defect by design, feeding you false data? How can you live if you cannot feel no touch, no taste, no smell - nothing that made the life nice? And then if you do make yourself feel some of that - you know for sure that your feelings exist only because you put an electrode in your own brain! You're deceiving yourself! Etc.etc.etc. It can be overcome (with wisdom, stubborn determination, philosophy education or some other way), but it is still much of a problem (also existing in flesh-bodied lives, but to lesser extent).
So whether it is practical to move on to robo-body or not is up to each person, balancing on whether the immediate physical gains outweight (or not) the potential mental problems it can create. So yes, while "flesh is weak", indeed, it allows for happier life on average. "Ignorance is bliss", in a fashion.
