When they get rid of or drastically reduce the number of flight attendants in the back, then I will start to think they have a chance at reducing cockpit crew. Yes system automation got rid of the FE, but pilot redundancy is paramount in safety.
They can easily get an automated galley cart on tracks, self serve beverage and snack stations and pre-programmed announcements for welcome and emergency scenarios, even if that requires some cockpit modifications with a few additional buttons.
