I'm against Designer Babies. Is there any rule in ethics that makes it wrong? We can think of many problems with it, like kids who have better genes will bully others, and the parents get to choose talents that might not be enjoyable to the kid later in life. Any other problems that you can think of? Thank You for your time! Sincerely, Bailey
