The said that about the 5th though. Like I've personally talked to people who were actively working on the F35 and they were saying "last manned aircraft" in like 2011ish.
I expect autonomy to be a long steady improvement of taking on additional subroutines of increasing complexity of decisions being made along the way. Fly here, land there, kill that, go over there without being detected, etc, etc, until humans are making only a select set of decisions that will probably be randomly sprinkled at the high and low levels.
Kind of like how when we build a brick wall the "vision" and the actual laying of bricks still get done by human but all the intermediary steps are drudgery that can be trivially automated (not to say they are all automated, just that they could be if labor $$ vs software $$ penciled out that way)
