My biggest concern is that my siblings and parents have all signed up. So (more or less) my DNA is in this database, even though I have never interacted with the organization.
Gattaca is an amazing movie, it has aged so well I find myself having more and more appreciation for the amount of thought that went into the script.
I'm on board with the idea that it's going to be difficult to make the opt in on something like this respectful of the actual wishes of the participants, but they are at least partly working in that direction.
It's never about the data itself, it's about what the worst possible groups can do with it given some nation state backing.
There's a founder of a genetic sequencing and embryo selection start up that I talked to who said they were "inspired by Gattaca" and isn't shy about bringing that inspiration up[1] at any opportunity.
Their company's promotional material also isn't shy about selecting embryos for predicted intelligence, height, etc.
