Years ago, I once worked at a large sugar refinery on the east coast of the United States, operated by a company that is a household word. The refinery had a plant manager in his seventies. He had an enormous distrust of computers.
"They make mistakes," you know.
While I was there, we were engaged in updating and automating the factory floor. He only grudgingly accepted PLC's (Programmable Logic Controllers, an industrial hardened computer with no hard drive, programmed in a boolean language used for robotics and automation).
PC's were still new, the early PLC's were programmed with a dumb terminal. When the OEM's developed PC software to program the PLC, one engineer sneaked in a then state-of-the-art machine on a capital project. He told the plant manager it was the programming terminal for the new PLC controlled equipment he was installing.
When the plant manager found out it was also a computer, he went ballistic and ordered it returned. The engineer, in a Dilbert-inspired reply, told the plant manager he couldn't return the computer because he had already used some of the memory.
