"The way I see it is the only real test is to see if it finds the treasure or not. If it does, then I don't care if it is a box full of cockroaches or circuit boards packed with gold plated CPUs. If it works for finding treasure, I can use it to bring home the goods without understanding a single thing about how it works. "
I could not agree more.
But if it does not find treasure, that fact needs to be iterated as well.
