User blog comment:DeltaSquad5/What is your opinion of 'designer babies'?/@comment-1197011-20140530025938

The idea is pretty scary IMO. Of course, genetic engineering could perhaps be used to cure diseases, but it shouldn't go any further than there. Our genome defines who we are in ways that science still cannot explain or comprehend fully, and it's easy to see how messing with it can have unintended consequences.

Also interesting that you talk about Kryptonian society, but in 1901 waaaay before Man of Steel came out, H. G. Wells elaborated an even more extreme version of the same idea in his The First Men in the Moon. The Selenites are each born with a specific function in society and they literally cannot do anything else. There is one with a huge head who just "remembers" (stores information) like a living database; there is one with huge hands who just writes or paints, I don't remember now; the more humanoid ones are the farmers; and there are many others.

I've always felt extremely sorry for the Selenites...
