The columnist says to ignore the yuck factor when considering public policy, but -- I can't.  Shades of 1984 in the US , and now Aldous Huxley's dystopia draws nigh.

Even if we can resist the urge to create uber humans, do we really want to eliminate disease?  The world is getting to be a crowded place thanks to incredible advances in food production and medicine.  But if we all live to be 140, where will we go?  What will we eat?

While not the literary meisterwerks of 1984 or Brave New World, the next emerging dystopia could well be Logan's Run......or Soylent Green.

And if you are too much of a  snob for those allusions, I will throw in Swift's A Modest Proposal.
