Part of the reason Neil DeGrasse Tyson is so painful to watch/listen to (especially on his recent appearances) is that this over-preparation or expectation of specific talking points comes off as smugness, interrupting behavior, etc... is it this which hurts the flow of conversation and even seemed to exasperate Joe Rogan during their talk recently?
DeGrasse Tyson interrupts Rogan right before important words - punchlines. For instance, in the first clip, Rogan begins “what’s interesting is that the town is -”, and DeGrasse Tyson takes that moment to pattern break: “wait, wait, wait, have you seen that they did Starry Night in bacon?!”. Rogan blinks, stunned. His point about the town lost forever.
Regardless, it’s possible to be well prepared but not interrupt the person you’re talking to right as they get to the juice. I would suggest Sean Evans and Nardwaur as examples from the other side of the fence - interviewers - who are unrivalled in preparation and give their guests a chance to speak.
And I work in space exploration! I've seen 100s of better voices for science than him fist hand.
NDT wasn't trying to have a conversation, he was trying to put on a performance. He was using intonation, cadence, and speech patterns rehearsed for putting on a show, whereas podcasters want to have something more like a natural conversation.
This can actually be a problem when people try to study social skills and speaking habits from performers and then deploy those habits into natural conversations. It comes off as inauthentic and awkward.
