CRISPR, a new genome editing tool- Ted talk by Geneticist Jennifer Doudna

CRISPR, a new genome editing tool, has the potential to cure genetic disease, potentially opening the road to "engineered humans."

Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases ... but could also be used to create so-called "designer babies." Doudna reviews how CRISPR-Cas9 works — and asks the scientific community to pause and discuss the ethics of this new tool.

It has already been used for human trait selection, as we have seen in the three-parent in vitro fertilization for eliminating mitochondrial diseases.

Here is a   Ted talk by her regarding what is  CRISPER-Cas9 technology, the ethical and societal implication of the procedure in future.
