Personally, with the advent of gene editing I think breeding "superhumans" will inevitably become the way of the future.
It will likely only be available to those who can afford it and will create an even deeper rift between the "haves" and "have nots" than is already in place.
CRISPR is a really recent development, and I don't think people truly realize how earth-shattering this new technology will be. Natural evolution is dead for all intents and purposes and we stand at the brink of a new era where the reigns to our own evolution have been thrust directly in our hands. Shit's gonna be wild.
I acknowledge that social constructs are inherently "natural" as they develop over time and are shaped by their environment. Basically, they've followed the process of natural evolution.
However, it's also our understanding that evolution does not result in the "best case scenario", just something that vaguely fits the circumstances.
I think it's perfectly valid to "dismiss" social norms in the pursuit of something better because a lot of social norms just developed by happenstance rather than having real thought or wider considerations worked into them.
