air space all around the world is becoming open for drones. cargo planes will be the first to switch to drone operation. for the people pointing out that AI is not there yet - drones are piloted by humans on the ground. BUT: you can have multiple drones monitored by one person. only sticky situations need human attention. the flight time over the atlantic at 35000ft does not need humans on board, cause guess what, it is already being flown on auto.
think of the savings for DHL, UPS, FEDEX. no more pilots in the craft means more room (no cockpit, no life support, etc). pilots on the ground can follow different safety regulation for sleep periods. you can switch to any pilot during flight, not just the one in the plane. and liability is way cheaper, you can actually decide to crash the plane into the sea in case of a failure.
i would not invest in being a driver of any kind as a long term thing. trains, planes, automobiles - the writing is on the wall. subways already become automated, trains are next.
