This reminds me of Eliezer’s short story That Alien Message, which is told from the other side of the speed divide. There’s also Freitas’ “sentience quotient” idea upper-bounding information-processing rate per unit mass at SQ +50 (it’s log scale—for reference, human brains are +13, all neuronal brains are several points away, vegetative SQ is −2, etc).
