Beyond this horizon

As many already know, CRISPR/Cas9 as well as gene drives are revolutionary tools which hold tremendous promise. However, with promise sometimes comes peril, and that's doubtless the case with CRISPR. Desiring God's article "What's Wrong with Designer Genes?" maps out a brief lay of the land in terms of the more conspicuous bioethical concerns and considerations. Likewise "Gene Editing: New Technology, Old Moral Questions". I don't agree with everything, but the articles are a decent start. Apart from the bioethics, scientific and technical material could be recommended if need be.
