The new era of dirt cheap space launch costs starts when SpaceX successfully launches 100 tons to LEO on a previously used booster and starship, then lands them again. Given how few flights are scheduled from Boca Chica it's fair to assume it will be at least a year before that, possibly longer. However, in so far as the raptor engines have flown, the belly flop maneuver has been validated, and the full stack has flown, once they're landing the booster and starship following successful payload deliver we could say that the new era started when raptor first flew.
