You are having it up my back!!
What is healthy? Any of us have hundreds of "faulty/bad" genes. In the long turn it may give bad results. And how we will know couple will have an unhealthy child until that child is born? Screening.
Screening once the child has been conceived, And even then it can not tell everything. Screening will not tell if your child will be autistic!
Computers were very expensive few decades ago. Nowadays you can have pretty good PC of $1000 (and 10 year old PC you won't buy for $100). New technologies are always expensive, with time it will become cheap.
They will not be using an ipad or a Dell laptop!! Surgery is not cheap and the surgeons wages are not getting lower. The money required to conduct the research and experiments will cost an arm and a leg, someone will want their money back as well as the surgeons being well paid for doing it too.
