“We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next 10.” That’s a quote from Bill Gates and it applies to a number of different trends and situations, but I’m thinking about Blockchain, in particular. Other things in the past, such as railroads back in the 1830s and dotcoms in the late ‘90s, among others, are examples of this tendency to overestimate and underestimate the magnitude of change.
