Also seems that this is one of the easiest jobs to automate in the future. Keep planes from running into each other. How hard could that be? If a computer can drag a 9-dan Go champion up and down the board, it can do this.

I'm sure I'll be told differently any minute now, but... if I were a young person looking for a career, ATC is going to be very far down the list. Concerns about future automation will become a self-fulling prophecy once no humans are available to do the job.
