Ah, something in the Life Sciences.
A genetic screening is already done at birth to test for serious genetic and metabolic disorders.
Now it sounds as though you are referring to complete genome sequencing? Am I right? If so, then from someone who was a biologist first, my answer would be no. Granted the police can use DNA, from a scene, to aid in an investigation as we all know. It can aid in who is the father of who.
However, the list to how such information could be misused is not short.
First, we have the consent of the patient. Babies can't consent. Second we have the privacy of the patient. Do they not deserve their privacy. One cannot open their mail without a legal warrant so why open their genome?
The full sequencing is really complex as compared to what is done at birth. Some will cite cost which is very expensive today. Aside from that who is going to interpret this information and be able to link it to future diseases which we called penetrance? If one does have some terrible future disorder, known at birth, what are you going to do? Tell them and freak the child and parents out? Do some sort of intervention that may not be needed? Or, in some hands, eliminate the child?
Granted their are upsides but oh boy are there downsides. In a perfect world I wouldn't worry but this is an imperfect world with imperfect people. I can recall fictional movies about the creation of a super race (oh oh shouldn't have used that word but may apply) through cloning. Today a fantasy still or is your idea a possible start for those so inclined? A bad actor can't possibly get this type of information by themselves but if collected by hospitals and collated by governments one sure does make it easier now. I won't be around for that, and neither will Arnold or you, but...........
Wow, too serious for a Sunday so time to take the old truck out for a drive to relax.
