Never underestimate the ability of people to find ways to break your system.
My son makes a living doing that. After years of breaking my stuff, he is now a test engineer and breaks other peoples stuff for money.
He says his greatest skills are inventing new ways of abusing stuff, things that the developers would never think of doing.
that amount of intelligence throughout the universe is constant,
Favorite quote from a Monty Python song:-
Pray that there is intelligent life somewhere out in space, because there's bugger all down here on Earth.
