Singularity 1 on 1 is a podcast that has interviewed people associated with this forum, like Lukeprog, Robin Hanson and James Miller. However there seems to be a lot of inferential distance between the host and his guests. I think someone like James Miller or Yvain would make a better host for this type of podcast.

Side note, if you find podcasts almost unlistenable at normal speed, you should use Overcast, which has the best speed-up effects of any app I've tried.
