Truth. Not even close. I'll even expand on Rick's reason why, with one word:

NextGen.

How long has some version of NextGen been in the works? To my very specific knowledge, at least as far back as the mid '90s. While some advances have been made toward that effort, we are still not close to having a fully developed version of NextGen out there. If it has taken at least two decades just to push THAT out the door, how in the world does anyone think that mass automated flight is around the corner?

Barring The Singularity, I don't think any of us of working age will live to see fully automated passenger and freight flight. As someone pointed out earlier... they haven't even automated the vast majority of train traffic yet. What makes you think that air traffic will get automated on a mass scale before that happens?
