I get the feeling opposition to IQ enhancements (beyond fixing obvious problems) have been drilled into the public by scifi and frankly history. I don't see it turning out real well unless humility and empathy can be genetically engineered.

China has orthogonal moral hysterias. Again, someone will do it and they will have an enormous advantage, 8 IQ points per generation at worst and 60+ at best. Considering the effect on the tails of the distribution, the vast majority of scientific productivity will be from edited or selected individuals.

I guess we'll see if all those scifi authors are correct and they tear themselves apart as the "new humans" deal with the "old humans".

Would lifespan matter?
