There are technological issue and then there are ethical issues. I can say we are several decades away from making a baby just by stitching raw genome data. There are 30,000 genes in human genome. Think the number of possible combinations that can arise only choosing few good genes are optimizing for a developing a tailor made human being. And the ethical challenge is huge too.
