Boeing vs Airbus; iirc AirBus is more a fan of software controlling flight surfaces (turn a dial, computer determines if safe while moving the controls) vs Boeing preferring traditional physical controls.
I think planes could be fully-automated (efficiency and price), but wonder why there'd be a need for a trained pilot still (job elimination), and wonder how pilots feel about different plane controls: What use is years of unique flight control training if the air line enforces autopilot use? Is there passion telling computers how to fly your plane?
