1. Manhattan project: The Hiroshima bomb was only tested once. The Nagasaki bomb was a different kind and never tested in advance. The whole infrastructure to produce those bombs was created from scratch within three years.
2. ICMBs: It required to shrink down nuclear bombs to put them on rockets, develop the capability to steer rockets precisely enough over thousands of kilometer, create a whole industry around the manufacturing. Then scale it up to hundreds of rockets.
3. Put a man on the moon. Nobody died at the first attempt.
You could consider those three steps as an example of Gall's Law as they build on each other. However, I would say each of them is a complex system in itself.
For an example of a complex system (and how unintelligible they are), see this diagram of metabolic pathways in the human body: https://www.sigmaaldrich.com/content/dam/sigma-aldrich/artic...
This one sounds easy: by eating those unprotected eggs!
These designs aren't seemingly flawed, they are flawed. Evolution produces flawed designs by "design".
Evolution trends towards survival. One thing critical for survival is equilibrium of the ecosystem so on a macro level evolution will trend towards equilibrium even if that necessitates the need for flawed designs.
In fact, flawed designs are critical to ecosystem survival. It works because competing designs to the flawed design are also just as flawed.
An invasive species on an island ecosystem is a perfect example of an over efficient design destroying a local ecosystem and in turn eventually destroying itself.
This is why ebola didn't spread as far as covid-19. Ebola is too efficient at killing thus reducing transmission rate and burning out the local ecosystem and thereby destroying itself before it got too far. The less efficient virus is the one that spread across the globe.
The ideal virus is one that easily spreads and does no harm to its host, or even improves the survival of its host. Our bodies are full of these organisms, like our gut bacteria.
When the virus is introduced into humans it arrives as an invasive species overloading the habitat and destroying itself.
An irresistible force can't move immovable objects and vice versa.
Warm blood? A huge, complicated heart? Are you insane? The metabolism rates will be off the charts.
Record-breaking spin-up times before adulthood? Where the parent animals will have to actively care for their helpless young? And spend bodily resources to produce a fluid with which to constantly feed each one? How could they ever compete with a species that lays 10,000 eggs a year, dashing off after — or before — they hatch?
And yet, as They Might Be Giants put it, these disruptive designs, so seemingly flawed, made the difference between extinction in the cold and explosive, radiating growth.
P.S. Did you recognize the chicken-and-egg problem in the second paragraph?
