Scientific breakthroughs surrounding human gene editing, for instance, have moved medical treatments that seemed science fiction just a few years ago within scientists’ reach. Today, tools like CRISPR/Cas9 allow making modifications to the human genome in ways that are more efficient and safer than ever before. And the science emerges rapidly, constantly offering new venues for treating what used to be incurable diseases.The idea of editing the human genome raises questions that science alone cannot answer.
