Serious scientists are already discussing and ruling out sythesis embryonics as patently unethical avenues of study.

“The film Jurassic Park exemplifies this whole discussion. The scientists in the movie are so focused on the question if they were able to clone dinosaurs, that no one asked whether they should be doing it! This should learn us a lesson and make us ask ourselves whether we should be practicing synthetic biology at all. Other questions follow on this one: is synthetic biology inherently wrong? If we act out of a deep respect for nature and life, doesn’t this require that we let go synthetic biology? “
“...ruling out sythesis embryonics as patently unethical avenues of study”
So they are ethical?
