My recent interest in learning Japanese doesn't contradict the fact that I stopped using RSVP years ago because I didn't need to inhale information that way anymore.
FWIW, I may well use RSVP as part of a trance-assisted program of learning Japanese in the future. The simplest method of learning a foreign language is to age-regress to a pre-linguistic age and then grow up again in a community of speakers over a period of a few days. Obviously you want to be selective of the parts of your psyche you regress (so e.g. no one has to change your diapers.) If you can't get a community of speakers willing to help you you can do things like saturate with TV in the language, and then polish up afterwards. Anyhow, even with hypnosis one can't squeeze blood from a stone. That's why I was asking about resources and communities.
