In my opinion the BART kiosk employee is a bad example of a job that can be automated. The fact is her job is already automated and probably why we don't have 10 of those kiosk workers per station handing out tickets and processing them by hand.

Her job is really just catching the 10-20% of people who don't know how to use tech that need hands on support at the stations, and random other odd jobs at the station that in fact can't be automated or automated to the same level of quality.
