Thus far, there's been no way to completely recover from Cybernetic implants, and certainly not while they're still part of a person. Then comes along Kill Code and these new-fangled Cyberadepts, and suddenly with a single immersion you can get a full essence point back. Now, I don't care much about the balance, but the implications of what this means about Resonance.
Now, we know that Resonance is tied to Essence, like Magic is. But now we know that Resonance can restore Essence, in a way that Magic can't.
My question is, why do you guys think that is? I'd also like to point out that the Null seem to be of the belief that Resonance is meatspace-based, which implies that it's not actually a byproduct of technology, but a byproduct of living things. My theory is that Resonance is actually the aura produced when a living thing reforms nature to its own devices, and it's for that reason that it's only recently starting to show up--Not because more of the world is being reformed, but because that which was already once refined to meet the standards of humans underwent another layer of refinement and reformation(The Crash causing the Matrix to go wireless) and as a byproduct, almost doubled the presence of Resonance, until it met the minimum threshold for touching humanity, much the same as the Earth only recently had enough life on it to Awaken again.
