While I'm sure that someday fully automated aircraft with only one pilot/operator on board will become a reality I don't think that will be in my lifetime. The reason? Well, every civilian transport category aircraft which is on the drawing board and/or is intended to be produced over the next several decades has at least two people up front. Given that these aircraft will then be operated for several more decades I can safely say that someone who starts off in aviation at age 20 today would not see a civilian UAV by the time they retire at 65. Remember, it's already been a while since a new build aircraft required an FE, yet there are still many of those aircraft and those guys around, I'd be willing to say you'll see FEs around for another 20 years, even though the position is effectively "extinct".
