Changeup doesn't really get it. He won't be swayed, either.
He really needs to read up on these things a bit more. Heck, even real life experience can tell you that the idea you learn things from your genetic past is ludicrous (and I don't mean Ludacris, the rapper).
I'll answer ONE of his silly notions though: Why do people wash out of flight school?
Because being a pilot, or even a combat pilot requires a large subset of skills and abilities. It's not one single yes/no pass/fail thing. Every person is unique. Even identical twins have their own differences that set them apart. The reason people wash out of flight school is because the sum events of their ENTIRE LIFE up to washing out have added up, and whatever that value is, the Air Force (or branch of your choice) said it wasn't enough to meet their standards.
Please note, they can try AGAIN, LATER, in another class, after studying harder, and learning more! The ever-changing dynamic of their education will be re-evaluated at that point in time.
You can't just say "You're genetically a pilot or you're not" -- and a lot of your other statements border on the ignorant.
