Misunderstandings between c-levels, v-levels, d-levels are less confusing when viewed like electricity transmission.
High voltage. Good for long distance. Not good for getting things done (plug in your toaster at your peril). Longer arcs.
Low voltage. Not good for long distance. Good for getting things done (toaster friendly). Shorter arcs.
C, V, D are different voltages with different parts to play. Not better or worse, just different.
Now if that makes sense to you, then the missing piece for a working “whole” power grid is the translation between the voltages.
Ds can talk like Vs to be understood by Cs.
Cs can talk like Vs to be understood by Ds.
(This not “correct” but just an illustration of the step-down/step-up translation.)
But if a D talks like a D to a C…
or a C talks like a C to a D…
It’s bound to be a baffling, frustrating experience.
Thus I conclude midnight thoughts on timespans of discretion, communication, and cohesion.
