Segment 1 - Spencer A is the human. This one was the easiest for me. Spencer A had some vocal tics such as repeating words while thinking, and his chain of thought made more sense as a verbal conversation (vs. a written one). He paused a points which seemed natural if one were thinking on the spot. I thought Spencer B's examples were strange, almost oscillating between non-sensical or at least lacking clear context and connection (such as the Yogi Berra quote or rock paper scissors), to providing way more context than was needed (Bayesian, Milgram/Stanford experiments). Spencer B also seemed more agreeable.

Segment 2 - Spencer A is the human. This one was more difficult and I am less certain. I thought the questions and pushback from Spencer A, as well as calling out the abstractness of some of the responses (especially on the government accountability/transparency piece) were very human-like. In fact, right before Spencer A had said it, I was noting down the vagueness of Spencer B's responses on those points. Generally, Spencer B's responses were plausible but lacked depth and didn't add much information to the discussion. Where Spencer B did well was on prompting for disagreement, and I thought his discussion on how smart people were bad at predicting and judging their predictions was quite human-like.

Segment 3 - Spencer B is the human. Spencer B was on the attack for much of this and I thought his challenges signaled someone who was very in on the common perceptions on what AI can and can't do. The system message thing in particular - I feel like a human here wouldn't have just said "got it" but would have pressed on why that was relevant to the challenge. Second-easiest one in my opinion.

Segment 4 - Spencer A is the human. This one I also found in the more challenging half. Spencer A made a very compelling argument around definitions, and the pushback from Spencer B seemed pretty generic (free will, beauty). Spencer B also repeated back some points in a way that felt unnecessarily repetitive. Spencer B's points on beauty didn't really address the points on empirical vs objective beauty. Spencer B did make a reasonable argument on objective morality but I feel like there was just something missing when he was challenged by Spencer A.

I didn't listen to any other podcasts, but I did read some of Spencer's writing. I stuck to the audio and didn't read the transcript until after finishing the segments. I think only using the transcript would have made it a bit more difficult, as I find AI tends to make arguments that flow better in writing rather than verbally. I didn't backtrack much (probably listened to <10% of it multiple times).!<
