The other tech, sadly, includes blockchains, and it's specifically in the context of gaming/metaverse stuff, not btc. But it's a deep diving interview with two people who are constantly thinking about the future of tech (and yes, we get NS talking about some of his books as well).
I also love Neal explaining why he hasn't tried an Apple Vision Pro:
I simply haven't had the opportunity. I literally don't know how I would go about getting access to one, other than buying one and having it shipped to me, which I wouldn't be interested in doing. My drawer is full. The drawer where I put expensive goggles that I never use.
