Gattaca, I forgot about this movie. Q’s 23andme post reminded me of it.
https: //www.imdb.com/title/tt0119177/
In "the not-too-distant" future, where genetic engineering of humans is common and DNA plays the primary role in determining social class, Vincent (Ethan Hawke) is conceived and born without the aid of this technology. Suffering from the nearly eradicated physical dysfunctions of myopia and a congenital heart defect, as well as being given a life expectancy of 30.2 years, Vincent faces extreme genetic discrimination and prejudice. The only way he can achieve his life-long dream of becoming an astronaut is to break the law and impersonate a "valid", a person with appropriate genetic advantage.
Are they using our DNA data to breed a better version of man for the rich, and everyone else will be a sub-human slave class? Q always said follow the bloodlines. They’ve been doing it for centuries just without the benefit of technology. Maybe their inbreeding and arranged marriages has left them weak and they need to bolster their stock.
Sorry to waste bread, just a theory.
