I'm fully expecting in our lifetimes for CRISPR to be able to flip the genome or whatever in the body that produces sex hormones such that testes and ovaries could swap functions and produce the opposite sex hormone.
Between this and using your own DNA to apply to scaffolding to grow an organ, the future is bright. I also expect to see sex organs of the opposite sex grown in a lab from your own DNA and then transplanted into you, and the body wouldn't reject them.
Wouldn't the average Lemmy DM be the "Fediverse Chick" that was getting spammed since that's likely the only DM most people have ever received?
