CMV: Trains will become 100% autonomous before airliners.

To this day, we still pay schmucks to sit in trains. Whether or not they are playing a super active role in its motion or path is varied, and lots of cities have trains which are extremely if not entirely automated, but there are still thousands of humans who are actively playing a role in the piloting of trains.

I believe this is due to the high cost of automating vehicles performing very high stakes human transport, and the powerful grip of unions preventing the loss of jobs in these fields. I believe both of these hold true for the airlines as well.

If we’ve had close to a century since train travel fell off in the United States and you can still find a job driving one, it will take even longer for automation to replace pilots on airplanes traveling much faster, with more variability in environment, carrying a much higher percentage of the traveling public with more factors affecting safety of the cargo.

Both are already basically automated. The pilots and conductors are there for psychological ease of the public, and emergency actions. But they are both actually capable of functioning without humans currently, they are just not allowed to do so.
