Gene editing technologies enable people to directly change their DNA sequence by adding, removing, or replacing DNA bases. Today, for the first time, as Jennifer Doudna and Samuel Sternberg announced in their book, A Crack in Creation: Gene Editing and the Unthinkable Power to Control Evolution, people “possess the ability to edit not only the DNA of every living human but also the DNA of future generations” (p. xvi). The emergence of new gene editing tools, such as CRISPR-Cas9, prime editing, and dubbed SATI, has led to momentous advances in biotechnology as the new tools make gene editing faster, easier, less expensive, and more precise than ever before.
While gene editing technologies offer great promise, they may also introduce risks with far-reaching consequences. This post focuses on the possible “dark side” of gene editing technologies and addresses some threats that the technologies might pose to human lives. While nowadays some of those risks would be deemed “science fiction,” they should be in the back of our minds as we ponder the potential impact of gene editing technologies.
