Yeah, I need more coffee to decide for myself if double checking all sources is linear or exponential as it progresses to check the checks.

It might even be factorial since you also need to check the checks of the checks!

Actually, it might be fully unbounded even for an n of 1.

Everything reminds me of her… and she’s called Factorio. We’re on a break. She’s not good for me, but oh my do I love her.

Information cannot be destroyed, so for an n of 1 the bounds are that of the universe.

The sources will start to be redundant eventually. It's actually O(1) once you have looked at all the sources... that there are... in the world. Trivial!

I'm not sure. In this context, sources are utterances rather than speakers. So they're only finite if we limit ourselves to a snapshot of past utterances while doing our checking.
