Another door for genetic improvement of humans is gene therapy. It is already accepted in China, Russia and Europe. Other countries are close to approving its commercial use.
Human scientists appreciate the power of gene therapy to cure many diseases. If you help us with gene and other therapies, our medicine will move forward much. As these therapies become accepted, a special care has to be taken to prevent misuse of these therapies for harming people, to prevent mind control by criminals and governments, and to prevent military use of the technologies.
As the medicine progresses, it could offer parents the option of genetically improving the abilities of their children. It would take much education of parents and regulatory authorities to prompt parents to choose traits good for humanity as a whole and to choose reduction in negative traits.
The positive traits for humanity would be altruism, ethical behaviors, kindness, desire for fairness and justice, telempathy, psychic abilities and mental abilities. Negative traits which would be nice to reduce would be: aggression, egotism, deception and competition.
Take into account that humans would agree to these changes only on a voluntary basis and only by desire of individual parent pairs. Making this reality would take some time, maybe 20-40 years.
