Just for a bit of background, I wrote a series of papers on monetary economics, and then a book (Explorations in the New Monetary Economics, with Randall Kroszner) which argued that technological changes were going to fundamentally revolutionize monetary institutions and finance over the next few decades. Those papers start in the mid-1980s and the book comes in the early 90s. So I was primed to see this coming, but in fact utterly failed.
I just wasn’t expecting crypto!
When bitcoin first came out, someone sent me the link and I put it on my blog Marginal Revolution—we were one of the first places to report on it.
