| Summary/Abstract |
The gene-editing technique CRISPR—clustered regularly interspaced short palindromic repeats—is often depicted as a security threat because it could theoretically allow scientists or amateurs to edit the genome of a variety of organisms and potentially cause harm to humans, plants, and animals. The recent use of CRISPR by Chinese scientist He Jiankui to edit the genome of viable embryos, which resulted in the birth of twin girls, has exacerbated those fears. This article reviews the timeline of the CRISPR-babies experiment, highlights the challenges that contributed to the experiment's failure, and evaluates the risks of CRISPR's use for malevolent purposes. It concludes that although the potential for abuse is great, the technical obstacles are still too significant to allow successful modification that would threaten security.
