Gattaca Will Happen
The science fiction movie Gattaca takes place in the future where, through much greater knowledge of the human genome, a husband and wife can now adjust and remove any bad genetic coding that could lead to inferiority of any kind before implantation of the fertilized egg into the womb. The results are humans with perfect vision, olympian-tuned bodies and immune systems insusceptible to common diseases.
I believe this world will come to pass.
And while many will want to have children the "natural" way, businesses, schools and more will desire the genetic elite ever the more until the majority are convinced to go along - for the sake of their children.
It started with donuts, and we will assuredly become Gattaca. How can this not happen?
