The ethics concerns of this should be put right up there with genetic modification.
During her 2 pregnancies, my wife permanently lost most of her sense of smell, had a lower leg clot, and apparently a clot in her hip. That last one was only discovered a few years later when it turned out that the cartilage in her left hip joint was completely gone and she needed a hip replacement at a young age.
I also imagine it's pretty difficult to do mental health screening on a gorilla, let alone extrapolate to whether a human baby would turn out physically okay but mentally not so great.
Or we do the sane thing and stop treating clumps of cells like people.
