No, but NPCs who work on space magic science have repeatedly said that purely artificial brains won't work, we need brains to be at least partially natural. People have proposed similar methods (clones with VR training) in the past but the scientists said it wouldn't work. And I'm about 67% certain that they are saying that because they have already tried that and not because they like stealing people's brains.
Note however that brains don't have to be completely natural. There was a guy who was a clone with some genetic variation that was raised semi-naturally for a few years (assuming the story was true). We could probably use some sort of accelerated breeding program to do something like that, create a species of humans that are born and grow up faster (or just create them fully formed in vats with use of genetic randomizers or recombiners) but it would still take years to grow a proper brain, because they need those real experiences. The human brain needs those to work with space magic for some reason. And even then, it's not certain whether or not we could somehow make them be more potent at amping or better at certain tasks/calculations by selecting for certain traits. The yield will probably be semi-random or even diminishing.
If the thing about brains doing math is confusing you into thinking the math is needed to allow the use of amps, then imagine ampers like D&D clerics. They have no magic of their own and neither do their amps. They use amps to contact their god, the god of math. They communicate with that god by using math. And then that god in turn uses math to transform their brain, to put their brain in the correct state, in the correct arrangement of energy.
The way I think it works is this: Because the universe is breaking apart, certain arrangements of energy can cause certain seemingly-unrelated effects. So when the amp in your brain puts your brain and the amp in the correct state, the correct arrangement of energy, that certain arrangement causes a change to manifest in the world. But for some reason, that correct state relies on the human having certain experiences, perhaps because it doesn't just need the brain to be in a certain state for a certain moment, it also needs the brain to have the proper history, or something it can only get by interacting with the world and the math and space magic energy the world hides in it. Of course, I'm not a science guy and that relies on OOC information and speculation, so I have no way of testing that assumption.
The theory I like the most is that the math god has a certain "template" that is meant to recognize brains eligible for the use of space magic. Perhaps the math god is an AI, created by humans to allow them to do certain things, so they have programmed it with certain traits they thought defined humans. But something like "define human" is very broad and hard to define, especially in a sci-fi setting, so maybe that AI also recognized other species and beings. Or maybe the AI broke down or evolved in ways humans couldn't predict. Perhaps that AI hasn't been created yet, but the effects of its creation ripple on to the past or to alternate universes. Or maybe it's not an AI at all, maybe it's just humanity evolved into something alien and then sent to the past. Which is the reason we can't change the future even though the prophecies tells us that it will happen, because we can't fight causality. Or maybe we can, because going back to the past has created an alternate universe, like in Red Alert.
Anyway, that's just my crazy mind making theories out of vague hints. The only way to know for sure is to beak the Doctor's Cipher in the Doctor's cipher thread.
