to be quite frank, no, not all of the interviwes are worth it, but since they are podcast, it is very easy to skim to the meat in some. The more interesting are the ones with the non-designers, such as ucltural anthropologist Grant McCracken,,,

having scanned your profile and seen your interest on art film, you might enjoy Curtis Hillman's take on interactivity and cinematic space. He also makes films. Not revolutionary, but he points at relevant structuralist points of view which I think are worth discussing.

And there are a few others. Granted most interviews with cellebrity designers can be self fawning and not informative at all. All interviews are prefaced by a monologue on Millman's tribulations and personal diary which to some, can be on the egocentric side, but some are entertaining, nevertheless. For whatever it's woth she is eloquent and does bring foreign (interdisciplinary) perspectives to the usualy insular design discourse.
