The host is annoying tho. He talks so fast and being overboard with negative statement
"It would be interesting to see who dies first..."
The way that the guest was responding to the style of interview was very positive and productive. It seems as though the negativity was used to great effect in cutting straight to the hard facts underlying all of the usual glossy technical coolness of bitcoin. To get an idea of what happens when the interviewer doesn't challenge the guest and let's the conversation devolve into the usual marketing talk about idealistic scenarios, check out this interview of a bitcoin company CEO with Max Keiser:

edit: Looking at the comments people are leaving on the TC website, nearly all of them share you opinion. I think the interviewer went too far with his negativity at a couple points, and so I partially agree.
