I'm sure that machine learning will come into play at some point, but we aren't able to model complex organic molecules in order to understand or evaluate "healthy" on silicon. In order to use ML on actual organisms, you'd need a way to try a lot of different modifications and then evaluate them after actual growth. Doing that kind of experimentation with human embryos, fetuses, and beyond has huge ethical minefields as well as many biological engineering challenges.
