I've definitely always wanted to be able to record the goings on of my brain...but I don't think that we'll be doing it any time soon. Even just for a rudimentary transcript of an inner monologue, scientists would have to find (if they haven't already) where on the brain said monologue is either generated or perceived and further be able to translate electrical and chemical signals into a human language. Perhaps with extreme advances in AI there will be a deep enough understanding of the mechanics of thought to be able to convert those signals, but it'll be awhile. Or maybe hyperspace aliens will teach us to materialize memory through glossolalia...
