Change is always hard. Fully autonomous passenger carrying drones will be arriving about the same time as the volt powered Cherokees (which will be obsolete when they arrive). In 10 years rated pilots will be sharing the airspace with non-rated drone pilots. In 20 years one of the family cars will be replaced with an autonomous drone. Yup your drone will be a Ford , KIA etc.
The really big question is why CAE isn’t pushing to teach primary flight training in simulators. This is the future of flight training, not “sparky the wonder-Cherokee”. Why not do 80% of the PPL in the box? Negate the need to convert the Cherokee…eh…
God bless.
