>As an employee at a terminal, you have a) no reason to trust some software people who may have never seen one of them steel boxes up close, b) if this works, you or your colleague gets laid off, and c) if it doesn't work, you're now stuck cleaning up the mess the computer will inevitably make for you, which is way less fun than planning things yourself.

Also d.) It works sometimes so you get forced to use it and then it gets ransomwared and you're completely unable to work because they laid off so many people you can't fall back to manual operations.
