Seriously, the main difference between CRISPR and other gene editing technologies is the hype. We have had the technology to alter genomes for a long time; we do not use them on humans.
This scientist He was looking for publicity, nothing more.
Influenza kills far more Chinese than AIDS. Many Chinese have a variant of the major histocompatibility comp!ex, a protein involved in immune function, that makes them very susceptible to severe effects of influenza infection. Why didn’t He go after that, and potentially save more people?
Also, I find it highly disturbing that there is evidence of genetic testing of preborn babies up to 6 months old. That opens the possibility that He has been killing babies for research.
In other articles (not necessarily about CRISPR) there are scientists who strive for “near human” test subjects by doping human DNA into other “things”.
If they can create a “subhuman” class they believe they are ethically clear to experiment on “it” or harvest “parts” from “it”.
Just as if they can establish a “cure” using fetal stem cells there will be a demand and a “need” for such cells to be created to be harvested (creating human organisms to harvest parts).
