parents should not have the right to deny their offspring a chance to exist
but again here you are switching back from the population level to the individual level. Those offspring do not exist by default, there are no ‘offspring’ that the parents have ‘denied the right to exist’. There are only counterfactual offspring, who already don’t exist.
spy on their kids’ futures by reading their genome
this, on the other hand, may be more valid—because the parents will ‘spy on’ both actual and counterfactual childrens genomes (and select the former over the latter). But you still seem to be taking the rights of those children as significantly more important than the rights of the parents. But this (‘whose rights, parents or children’) seems like the fundamental crux that we are unlikely to shift one another on here.
Edit: and, reading through your other comments, there seems to be a question about the social impact of these technologies. This is then an impact on the rights of everyone—the parent, the child, and the rest of society. Also interesting, and I think it would be helpful to seperate out objections on the individual (parent/child) level, and on the society level, and I feel like they are getting muddled a lot here.
