can you imagine if we were mechanical, robot, instead of biological?
you wouldn't eat food and produce shit, you would just charge your batteries.
you wouldn't die even after serious accident, as long as your HDD was not damaged, all parts of your body could be replaced. even if your HDD died, a backup of your mind could be restored from backup into your new HDD
you could make clones of yourself, simply buy another robot, copy HDD contents into it. (wouldn't that result in war of clones though?)
I think the intermediate step will be to create a robot body and put real brain into it
we could also have women that wouldn't shit, wouldn't have periods. or just don't have women, they are useless if we stop biological humans
