We measure it in the distance something takes to get from one spot to another spot, right? In that context, we can measure how long it takes light to travel from a source until it arrives.

But dark is different. Dark exists where light does not, and light is limited in source and duration, while dark is not. In the absence of light, can you describe how quickly darkness travels? Does it travel? Can it travel?

So like I said, it either exists or it does not (or, in place of "does not", is masked by light). It doesn't travel, ergo has no speed.

Think about it like this: To an observer, if I left and arrived at the same time, did I go somewhere very quickly, or nowhere instantly?

Well, in terms of definitions, to leave you must go somewhere else, and to arrive you must come from somewhere else. So you can either move instantaneously, or you need better wording.

I'd say not until it's actually confirmed in any sense. Hearsay from random journalists is rather meh.
