Mechanical and Synthetic autarky
With extensions of his limbs and mind, with machines and beaker flasks, 1940's Civilized Man could top any physical feat that nature's most noblest creatures could ever hope to do.
And he had a fist full of recent new world records to prove it.
For in this new era of unending progress, man could now fly higher than an eagle, deeper than a whale, move faster than a cheetah.
Dig deeper than any mole, live higher up a mountain than any polar bush.
Sure a penguin lived at the edge of Antarctica, but had any penguin gone to the South Pole - or the North ?
Had he, had he ??
Smelter fires hotter than any volcano, electrical sparks bigger than any lightning strike.
On and on it went : even man-made silk finer than any mere worm could weave.
Designer meals (and soon, designer babies) better than mother could ever make.
Who needs Mother Nature consuming calories when her jobs could be done better by engines and beakers ?
So, about those plans to "kill off all the smallpox virus on the Earth, as 'life unworthy of life' "?
Just a start, buddy, just a start ....
