Two reasons why pilots will always be on flight decks of RPT aircraft:
1. The public need someone to trust for their safely and to keep them informed and secure in an environment they don’t understand. Without people to trust up front, they won’t get onboard.
2. Aviation law needs someone to be held responsible when things don’t go as designed. Without a PIC to be held responsible, the law will need to hold the operators ( ie CEOs) responsible for technical operations they will not comprehend. Then CEOs will have to employ staff who can comprehend these operations to fill this gap - ie….probably pilots. (!!??)
