As societies become more developed they have lower birth rates. If we are going to have fewer children, don't we have a responsibility to have better children? Healthier, smarter, more talented children?
An article in The Telegraph (U.K.) reports the views of the editor of The Journal of Medical Ethics, Professor Julian Savulescu. He believes we have a moral responsibility to have saner, less violent children.
If parents intend to try very hard to raise one or more children with all the post-delivery advantages possible, why not increase the pre-delivery or even pre-conception advantages as well? In other words, genetically improved children.
