Maybe you should consider the fact fighter pilots have the highest "real world" SA on what actually works/is required in the mission sets currently executed by fighter aircraft (referring to well beyond CAS...we won't be doing this stuff forever). Of course there is a sense of self-preservation when it comes to future jobs, desire to continue in manned aviation, etc...I won't deny that. However, dudes deep in RPA programs, etc. are so removed from said missions/have ZERO SA on the actual missions (beyond what they've read/been briefed), they work with "conceptual" SA. It's all theory, works-great-in-a-vacuum, etc. It shouldn't be a surprise when folks who actually sit in the seat and fly shoot valid holes in the "realistic ability" of different programs.
Yep, we'll eventually get there, but there's real, valid reasons why people are not the level of RPA-lovers others think they should be. And it has extremely little to do with wanting to preserve our future jobs.
