Here’s why you’re right, and wrong  

Autonomous aircraft flight is indeed becoming truly remarkable. In jobs where there are no passengers (some utility, ENG etc…), I fully agree with you. Those jobs will be outsourced to aircraft without pilots. The fallacy in this thinking though is when you add passengers to the equation. It will take decades to convince passengers that unmanned aircraft are safe enough to fly in without the use of a human pilot. Think of the airlines. Large commercial jets can (and do) fly themselves. Convincing the general public to climb into a pilotless aircraft is the real struggle.
