So if science and technology allowed for humans to become almost completely bionic would you be up for it? I'm talking about replacing as much of your body as possible with titanium, perhaps comic book style. Sure there are scientific boundaries and balances that would have to be met, but assuming most of the human body can be done away with and your brain can be hooked up to a cyborg type of machine, thinking every bit as clearly as you can now, would you do it? I kind of consider your brain as "you" since just about everything else can be swapped out during transplants. A brain transplant would result in you waking up as whoevers brain was just put into you. (Let's remember we are assuming all of this is possible for the sake of the question) Pros: You'd be very hard to kill, considering you wouldn't really be at risk of losing blood. I guess blood would be made inside your new body somewhere and circulated to your brain, housed in a titanium casing (skull of some sort). Of course you could have a realistic looking skin and outer appearance. Terminator style. You could probably easily live several hundred years.. Cons.. Well, you wouldn't really be human anymore for the most part. You'd probably need repairs and/or upgrades periodically. I assume instead of eating there would be another way to provide proper nourishment to your brain. You'd essentially be a brain inside a highly advanced robot. So who would do it?
