"modern medicine that will result in mankind accumulating more and more genetic defects."
Citation needed...
A lot of autosomal recessive genetic disease is a result of humans reproducing within their in-group, making the likelihood of two carriers of the same variant having offspring with that expressed variant. BRCA1 / BRCA2 in the Ashkenazi Jewish population are a common example.
Nothing about medical genetic testing will directly cause more genetic defects.

- foenix 6y agoUpon second reading it appears I have misunderstood your comment. My bad!
- lazyasciiart 6y agoI believe the comment is saying that medical genetic testing and selective abortion is necessary because modern medicine protects people with e.g BRCA1 or cystic fibrosis.
- Symmetry 6y agoThe problem is that every generation has new de novo mutations. Mostly they don't do anything, very rarely they're positive, but some are bad. It used to be that only half of children survived to adulthood which produced enough selective pressure to remove new deleterious mutations, but that thankfully doesn't happen anymore. This isn't a problem in the short term but if we don't introduce something like pre-natal selection we'll eventually wind up back in a situation where half of children don't survive to adulthood despite modern medicine.
