"There is nothing more temporary than a permanent solution and nothing more permanent than a temporary solution" needs to be designated as a rule or law akin to Hofstadter's law or the Ninety-ninety rule. As a placeholder until a better name is chosen, I propose we call it Foundart's Rule.
Googling for "Daugherty's Law" only returns law firms, and a cursory reading up on Richard Daugherty doesn't seem to indicate anything of the aforementioned.
So, yes, would appreciate a citation so we can all learn a new trivia of the day.
