Agree.

A lot of this "controversial" stuff isn't ie therapeutic cures for sickle cell, a single nucleotide mutation with devastating impact on quality of life.

For some like myself with CDH1(https://en.wikipedia.org/wiki/CDH1_(gene)) it means a total gastrectomy is the prophylactic solution to avoiding hereditary diffuse stomach cancer. CDH1 is a more complex mutation than sickle cell.

These technologies are capable of doing more good than harm for society in the near term. The dystopian visions are not without merit, but that's the general rule of thumb for technology in general. A loss of genetic diversity is likely the gravest concern. Some mutations have benefit ie sickle cell vs malaria, but others like CDH1 have mostly been slipping under the evolutionary radar. There are multiple variants of concern and the mutation is just independently occurring across the global human population irrespective of any special heritage. There are other cancers/maladies just like this that medicine has no good solution for. They don't noticeably impede genetic reproduction so it carries from generation to generation.

For now most sane people are not considering germ-line modification. I would expect that to require multiple generations of study to even broach the subject.
