[2021] Does your colonists also turn into swiss cheese into the mid game?

At this point all my colonists have at least 2 bionic parts and a lot of them have missing fingers and toes. Besides bionic parts I have to run a full time organ harvesting business to replace missing organs and at this point they are all more machine than human. How do you even prevent this? Should I even prevent this, I love my colonists running around like they are at a sonic convention.
