Murphy's law ...

Aside from the somewhat sensationalist title, Unknown Killer Robots, the Netflix documentary's a good primer on the implications of creating AI driven autonomous bots able to kill with great efficiency using open ended tech poised to not only change warfare as we know it but also in showing just how easy it is to change the mission of a given AI entity from good to bad by simply changing a "0" to a "1". The other interesting take on this piece is the fact the weapons guys are so confident their code is perfect, that nothing can go wrong and that the product in question will prevail over the enemy with little concern as to how Murphy's Law can impact the deployment of said tech in an enterprise as unpredictable as the one known as war.

The perceived perversity of the universe has long been a subject of comment, and precursors to the modern version of Murphy's law are abundant. According to Robert A. J. Matthews in a 1997 article in Scientific American,[3] the name "Murphy's law" originated in 1949, but the concept itself had already long since been known to humans. As quoted by Richard Rhodes,[4]: 187  Matthews said, "The familiar version of Murphy's law is not quite 50 years old, but the essential idea behind it has been around for centuries. […] The modern version of Murphy's Law has its roots in U.S. Air Force studies performed in 1949 on the effects of rapid deceleration on pilots." Matthews goes on to explain how Edward A. Murphy Jr. was the eponym, but only because his original thought was modified subsequently into the now established form that is not exactly what he himself had said. Research into the origin of Murphy's law has been conducted by members of the American Dialect Society (ADS).

"everything that can go wrong will go wrong".
