Interesting question. But humans are constantly evolving. Evolution is not one leap forward after another, but a series of tiny tiny steps that add up over thousands of generations
Hah, I love the question. Intuition might tell us that it's slow, but I'd say it's equally fast. Dark is just the absence of light, so it takes light the same time to skedaddle as it does to bathe us with its warming glow!
The speed of dark must go from the SOL to zero. Light, as we know it, is photons acting on our retina-brain. If the source of the photons ends, then darkness spreads at the SOL until it passes you; it then falls to zero as there are no more photons
