Fear of change? More like, "steam rolled by change." When I'm at work I'm responcible for keeping hundreds of computer controlled machines running. Machines from the fifties that have had computer controls added to them. Kind of like your first gen Bird with a serpentine, computer, laser guidance system, radar, plasma screen, microwave... The engineers have no bounds with improvements. They ask me to add a laser hole checker and give me a piece of thin gage sheet metal bracket and a few screws and say, "Add the laser". Later that day, "Hey, the hole checker isn't on location." I say,"No snit, somebody bumped it?"
