I think that the MTA and CFA original ingredients were the previously superior alien races because some of them if I remember correctly were mentioned to have extraordinary psionic based powers which is how they essentially have dominion over the galaxy before the humans raised up through the use five scrolls and technologies that the aliens don't have. Supreme Sage could be experimenting using expert pilots because the big two don't wanna share the psionic aliens or the alien ingredients are almost out of stock.
I would think Ves can easily accept conspiracies theories. It's good for him to examine the data before jumping the shark. It's not guaranteed the Big Two are secretly extracting the brain of experts pilots once they died. Anyhow, I kind of revoked Ves right to be offended because of experiments on humans. It's great to see that only the former lifers scientist is panicking.
