Programming languages are turing complete...the boundary is mathematics itself.
Unless you are going to take the position that neural systems transcend mathmatics (i.e. they are magic), there is no theoretical reason that a brain can't run on silicon. It's all just numbers, no magic spirit energy.
We've had evolutionary algorithms and programs that self-train themselves for decades now.
mathematics, has a problem with uncertainties, and that is why math, as structured cant do it. magic makes a cool strawman, but there is no magic, you need to refine your awareness of physical reality. solid state silicon wont get you where you want to go. you should look at colloidal systems [however that leads to biology] or if energetic constraints are not an issue, plasma state quantum "computation".
also any such thing that is generated, must be responsive to consequences of its own activities, capable of meta-training, rather than being locked into a training programming. a system of aligned, emergent outcomes.
