What is scary is that elites now have unprecedented control of the genome.  This process began as control of Nature, sadly sanctioned by the father of the Scientific Method, Francis Bacon.  He was admirable in many respects as a philosopher, but his "Go ahead and abuse Nature because she gets off on it" philosophy has wrecked western culture.  Some sources suggest that Bacon may have embraced vegetarianism at some point, suggesting perhaps that his views may have changed.  Sadly, though, the "animals are biological machines" meme survived him regardless of whether or not his views changed.

Now, the control of the genome is nearing perfection.  This means that we are also going to see control of humans.  It is the inevitable next step.  Totalitarians like Hitler and Stalin came close, but could never quite make it.  My sad feeling is that the real creation of a global Panopticon will all be done in the name of "democracy."  What will really happen is that our DNA itself becomes owned by corporate interests more than by governments per se.  But, DNA owned implies that we become property.  Once a gene is patented (already legal in US law!) we become property by definition.

The issue of eugenics is relevant today.  It is as relevant as it ever was.
