Are we step closer to making babies only with desired traits?

When a rogue researcher in China revealed in 2018 that he had used CRISPR to create three gene-edited children, his actions were almost universally condemned by biologists. The main objection was not that gene-editing babies is wrong in itself, but that the CRISPR method used wasn’t safe and had a very high risk of causing harmful mutations.
Now, a team in the US has used an improved form of CRISPR, known as base editing, to edit healthy embryos, and shown that it can be done without introducing unwanted mutations.
