The dystopian Brave New World of designer babies may be upon us, courtesy of Chinese scientist He Jiankui.

The physics expert, who has no experience with human clinical trials, announced that twin girls had been born from embryos that he “gene-edited” in an attempt to increase their resistance to HIV.

And that is not good news.

In fact, his announcement on Monday — bizarrely made on YouTube — was met with worldwide condemnation, including from HIV researchers and some 120 Chinese scientists who denounced his work as “madness.”

Elsewhere, scientists criticized the secret and unjustifiable testing of a hypothesis when experts have no idea what the repercussions and possible mutations will be for these children, Lulu and Nana, never mind future generations as the altered DNA is passed on.

But what is known is scary enough. People without a normal CCR5 gene, the one He edited, have a higher risk of contracting other viruses, such as West Nile, and dying from the flu. And the twins’ risk of cancer could increase dramatically.

This experiment could also lead to the slippery slope of trying to create superhuman designer babies, a path that the late Stephen Hawking warned could lead to the end of “unimproved humans.”

“The Pandora’s Box has been opened, but we may still have a chance to close it before it is irreparable,” Chinese scientists said in a joint statement.

Their words should be heeded in laboratories around the world.
