I think there's actually some debate about how just the right amount of automation can be dangerous in planes. Automation works great in nominal conditions but can leave pilots unprepared to handle bad situations.

There was a really interesting article I read about this regarding the Air France plane that crashed a few years ago (I think it was this: https://www.vanityfair.com/news/business/2014/10/air-france-...). Similar things even came to play with the recent Lion Air crash, although there was also a lot of negligence and crappy maintenance.
