Have you ever been to an oil and air filter warehouse?
Some are more common than others, but there are hundreds of different types, and some of them vary by a millimeter in diameter from the more common ones.
They couldn't design the inlet to fit a pre-existing filter already in circulation, no sir, instead of any sort of compatibility they felt compelled to make up their own fucking specification and parameters that varied by a tenth of a percentage point.
That can only be the work of engineers, and from the looks of that oil filter warehouse, or from the different types of electrical sockets, the contrary bastards are everywhere, they REFUSE to meaningfully communicate with each other, and will NOT listen to reason.
More recently, look at crypto. For every well-meaning and thoughtful endeavor like Bitcoin or Ethereum, there are ten thousand shitcoins. Many are just greedy con jobs, but many are also due to stubborn and petty, noisy squabbles over minutiae. Suddenly the whole damn space was a hive of useless noise and confusion.
