Answer:
One argument in favor of the ability to change a child's genetics before they are born is that it could potentially allow parents to eliminate or reduce the risk of serious genetic disorders or conditions that their child might otherwise be born with. This could potentially improve the child's quality of life and reduce the burden of care and treatment on the child and their family.
However, there are also significant concerns and objections to the ability to change a child's genetics before they are born. Some argue that such interventions could potentially lead to the creation of "designer babies," with parents choosing certain traits or characteristics for their child based on societal norms or personal preferences. This could potentially lead to the further exacerbation of social inequalities, as wealthier individuals may be more able to afford these kinds of interventions.
