If we're getting rid of pilots, why not cabin crew as well? Passengers could get food and drink from a vending machine, and be responsible for evacuating themselves in case of an emergency, just like how every Public Transportation bus or metro operates today, even the driverless ones! /s
That's because contrary to popular opinion, cabin crew are all about service and very little about safety. IIRC there was a case somewhere in Asia where a flight attendant broke her arm trying to open a door during an evacuation. Unless we see in the future passengers hibernating in pods during flight (and handled on the ground by gate agents/baggage handlers) you'll always have cabin crew because premium airlines have service standards to uphold, and budget airlines can turn cabin crew into revenue earners (by selling stuff) and make them perform miscellaneous tasks such as cleaning the aircraft.
The trend is not about removing the pilot, but
de-skilling the profession so that it can be performed either by people with less training and less pay, or by the cabin crew. A pilot in the future may be expected to 'manage' the automation during takeoff and landing, and serve drinks/sell scratch cards in the cabin during cruise.
