From the article:

"The Third International Summit on Human Genome Editing has concluded, and experts have come to a consensus that, “Heritable human genome editing remains unacceptable at this time,” according to their statement. There has ben a lot of hype surrounding the Nobel-prize winning tool CRISPR-Cas9, and it has been revolutionary for the biomedical laboratory. But there appears to still be a significant number of technical challenges that have to be overcome before this approach can be used to edit the genome of human embryos. This is even before we grapple with the ethical implications."
