No, this is not pedantic. An autopilot is a complex system that needs full time management. It looks like this [1], and you need to correctly twiddle the dials every few minutes to get the plane to do what you want. It's not a button, it doesn't avoid traffic, and it doesn't know about the broader flight plan. Even fancy autopilots that can follow waypoints and intercept a localizer and autoland and all that - managing them looks more like programming a crappy computer than pressing a button.
