Automation generally goes along with a transition to more "self-service" approaches that require the user to model internal states and workflows of whatever they're dealing with.

This is even true for things as seemingly non-technological as getting to your flight once you arrive at the airport. People who are used to dealing with a service desk might just show up with their printed ticket without even having looked at it, take it to the counter, and expect instructions on what to do next without having read or considered all the fields present on the ticket.

It's not just about understanding the technology, but sometimes about understanding the business, policies, whatever. When a human agent or customer service worker is handling that stuff for you (typical in the pre-computer age), you barely have to think about that stuff and even if you're told, it can be "in one ear, out the other". Automation very often means pushing a requirement of more understanding onto customers/users.
