I think this is the only thing Nostr fixes. It has a lot of other issues, I feel which makes it difficult to scale. Like you can't block anyone, just mute. It's only the text that is distributed, media is still centralized, etc.. You cant stop someone from following you. Metadata about you gets leaked to the network like who you are muting. It doesn't work well if you use two different clients, like desktop and android.
I don't think the light "knew" from the beginning. The light started in a state of superposition, right? Both unholy and holy. Once it hits the vampire, only the unholy light is reflected, acting like a sort of filter similar to a polarizing lens.
Well, if we treat incoming light as a quantum superposition:
|light⟩ = α|holy⟩ + β|unholy⟩
...and assume that vampires reflect only unholy light and absorb holy light, then anything directly part of the vampire’s "system" filters light this way.
So I guess the question becomes, "How does the filtering happen?" Is it by physical surface, or is there some kind of quantum holiness field that absorbs holy light nearby?
I feel like heavy industrial would be better because of the noise pollution.
