Autopilot, cruise control, automated scripts – these are all technological solutions to having to do things that don’t really require much nuance or thought.
If you commit to driving 65 mph and you have open road in front of you, why think about how much pressure you need to put on the gas pedal? If you need to change the image size of a list of photos and you can automate the task, why not use the script Photoshop gives you?
However, when you are interacting with another human, going on autopilot in your interaction shows you don’t care about them. It shows that they are not worth your attention.
There is a time and place for automation, but dealing with other people is neither.
