io9 has dubbed Geek's Guide to the Galaxy episode 19 the "best discussion of human identity and the Tuvix Voyager episode ever."
Editor Annalee Newitz writes: The highlight of the episode is Adams and co-host David Barr Kirtley interviewing Robin Wasserman, author of Skinned, about how you transfer human consciousness into a high-tech body. This later kicks off a whole discussion between Adams and Kirtley about whether transporters are really killing you and then creating a perfect copy at the other end of the transporter beam. And that in turn leads to actual intelligent commentary on the Tuvix episode - you know, where Tuvok and Neelix are merged into one Super Awful Being as a result of a transporter accident? Yeah. You've got to listen.
