    I agree with the fact that for such advancement in science & technology, both scientific as well as ethical points should be kept in mind especially in case of designing forums like babies.

    Scientific considerations will improve the genetic compatibility, responsiveness and alignment of the design towards a sustainable and feasible goal which is required for the easy study of genetic basis as well as abnormalities adapted in humans. Scientific area is crucial and carelessness with it can lead to unwanted consequences in future such as mutation and editing of desired genes to undesired ones.

    From the ethical perspective, one should respect the human dignity and human emotions as these two can have long time consequences on the various designs launched in the market. Social inequalities can lead to injustice to some people. Without the utter consent of the individuals no programme should be launched or established just for the sake of financial gains. This will create havoc not only in an individual but also in large communities.

    In order to balance both scientific and ethical approach, the designing committee must look for collaborations and work in a team for different and sustainable ideas. Financial gains are there as long as people and large masses support it.
