>or else we wouldn't need hundreds to thousands of drone operators in the Ukraine war

I don't think this is the reason the systems are not fully autonomous right now ("fully autonomous" here meaning that they can complete the kill chain independently, no HITL). Even if we assume it true that the drones are not "good enough" to be at parity with a human operator, if you had an essentially limitless amount of them, would you really waste the manpower on operating them in FPV mode? You would not, you would completely saturate the battlefield with them. Thus, as it was in the beforetimes and ever shall be, logistics wins wars.

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)

I mean, they wouldn't think that, would they? It would put their pilots out of a job. But most flying has been done by autopilot long before AI, and even if/when you need a human in the loop, why would you want to put that human in the cockpit rather than safely in Virginia?
