This is hands-down one of the most original ideas I've seen in any podcast, ever.
As for execution: arguably middling. Towards the middle, when the episodes run towards human-dictated episodes, they are weaker, but overall, fairly good.
I'm halfway through episode five as of this afternoon.
It reminds me of
Tron, and not in a good way. The excessive anthromorphisation of the characters is a bit grating. These are
thoughts, at most "a sentence or two", and yet they seem to be fully people with high-functioning thoughts of their own, just like the self-aware
programs in
Tron (shit, even "
Hello World" is pretty much an AI in the world of
Tron). I'm not sure yet where the action is taking place, but I'm guessing it's within the brain of some unidentified human; probably an elderly person in failing health.
And the line "Molly smiled" ... these "thoughts" are explicitly described as being without facial features or other identifying characteristics (other than the number on the chest) so that line really stood out for me. Yes, it is revealed shortly thereafter that she has developed a personal appearance including facial features, but that's not known to the reader/listener at the moment that she "smiled"; seems like sloppy writing to me.
Is that what you mean by the "execution" of the idea? ("middling" seems an overly generous rating.) It
is an interesting idea, and I'll keep listening to see where this is going, but I keep shaking my head all through it.
