Buried (at least for me) in the flood of political news these past weeks was something potentially far more important. It appears that a researcher in China has made the first human embryo gene edit.
It is perhaps not surprising that the guy who did it is not actually trained in reproductive research. His degree is in biophysics (from Rice University in Texas) with additional work at Stanford University on DNA.
Another surprise: he wasn't trying to correct a genetic defect (say something like sickle cell anemia). Rather he was trying to create an immunity to HIV transmission -- which can already be dealt with via cleansing during IVF.
Still, it's the first step towards a couple of science fiction staples: a) genetic cleaning, or b) genetic enhanced human beings. Depending on your view of how technology is likely to get used. There has, not surprisingly, been an outcry. Some of it because the work wasn't in accord with the law (even in China), some because there is some question whether the parents were clearly informed about what he was proposing to do, some because the technology isn't to the point where you can be sure that you will get the edit you want while not getting changes you didn't intend.
There has not, that I have seen (as noted, I barely caught this at all), been any outcry about "playing God" or about the threat of artificial supermen. But given the reaction, a couple decades back, to cloning (and that was only a sheep, not a human being), not to mention to GMO foods, it seems likely to happen once people actually notice. Perhaps after the kids (there appear to be 2 or 3) are born....
We live in interesting times.
